I designed a graphical chart detailing various historical events as seen from a Biblically conservative viewpoint.

This is a very good question: How could I have Terah as having Abram when he was 130 rather than 70 as verse 26 seems to indicate:

26. Now Terah lived seventy years, and begot Abram, Nahor, and Haran. Genesis 11:26

The verse almost makes it sound as if all three sons were born in the same year, as if they were triplets. But they were not triplets. They were not even born in the same year.

It turns out that Abram was not the first born. Haran was the eldest son of Terah. Abram was the youngest son and he was born much later!

So, why is Abram listed first. It is because he is the most important to those reading the book of Genesis. He is the son who the promise will come from.

To help confirm this lets look at Genesis 11:32 -12:4

32. So the days of Terah were two hundred and five years, and Terah died in Haran.

1. Now the LORD had said to Abram: "Get out of your country, From your family And from your father's house, To a land that I will show you.
2. I will make you a great nation; I will bless you And make your name great; And you shall be a blessing.
3. I will bless those who bless you, And I will curse him who curses you; And in you all the families of the earth shall be blessed."
4. So Abram departed as the LORD had spoken to him, and Lot went with him. And Abram was seventy-five years old when he departed from Haran. Genesis 11:32-12:4

This Scripture says that Terah dies when he is 205 years old. Then God tells Abram to leave for a country he has never seen before. So Abram leaves. When he leaves he is 75 years old!

If Abram was born when Terah was 70, as Genesis 11:26 seems to indicate, then Abram would then be 135 years old when Terah, his father, dies at 205 years.

But this idea does not agree with verse 4 which says Abram was 75 years old! So, if we take the hint from Genesis 12:4 and realize that Abram was actually 75 when his 205 year old father dies, that means that Terah was really 130 years old when Abram was born.

PS - My Computer Bible has the free Smith Bible commentary. Here is what it says about Genesis 11:26:

Verse 26. [And Terah lived seventy years, and begat Abram, Nahor, and Haran.] Haran was certainly the eldest son of Terah, and he appears to have been born when Terah was about seventy years of age, and his birth was followed in successive periods with those of Nahor his second, and Abram his youngest son. Many have been greatly puzzled with the account here, supposing because Abram is mentioned first, that therefore he was the eldest son of Terah: but he is only put first by way of dignity. An in stance of this we have already seen, Ge 5:32, where Noah is represented as having Shem, Ham, and Japheth in this order of succession; whereas it is evident from other scriptures that Shem was the youngest son, who for dignity is named first, as Abram is here; and Japheth the eldest, named last, as Haran is here. Terah died two hundred and five years old, Ge 11:32; then Abram departed from Haran when seventy-five years old, Ge 12:4; therefore Abram was born, not when his father Terah was seventy, but when he was one hundred and thirty.

When any case of dignity or pre-eminence is to be marked, then even the youngest son is set before all the rest, though contrary to the usage of the Scriptures in other cases. Hence we find Shem, the youngest son of Noah, always mentioned first; Moses is mentioned before his elder brother Aaron; and Abram before his two elder brethren Haran and Nahor. These observations are sufficient to remove all difficulty from this place.

Yes you are correct. Noah did not have triplets. Because Genesis 5:32 introduces them that way, I did the same on the chart. It says:

32. And Noah was five hundred years old: And Noah begat Shem, Ham, and Japheth. Genesis 5:32

We know that Japheth is the oldest of the three sons:

21. And children were born also to Shem, the father of all the children of Eber, the brother of Japheth the elder. Genesis 10:21

We also know that Ham is the youngest of the three sons (v24 below).

22. And Ham, the father of Canaan, saw the nakedness of his father, and told his two brethren without.
23. And Shem and Japheth took a garment, and laid it upon both their shoulders, and went backward, and covered the nakedness of their father. And their faces were backward, and they saw not their father's nakedness.
24. And Noah awoke from his wine, and knew what his youngest son had done unto him. Genesis 9:22-24 1901 American Standard Version

Many versions have younger instead of youngest in verse 24. But lets look at what the meaning of the Hebrew word actually is:

06996   "kaw-tawn" or
            "kaw-tone"

from 06962; TWOT - 2009a,2009b; adj

KJV - small 33, little 19, youngest 15, younger 14, least 10, less 3, lesser 2, little one 2, smallest 1, small things 1, young 1; 101

1) young, small, insignificant, unimportant 1a) small 1b) insignificant 1c) young 1d) unimportant

I looked at the Clarke Commentary which also said: "Ham was certainly the youngest of Noah's sons"

We also know that Shem was born when Noah was 502 years old, and not 500:

6. Noah was six hundred years old when the floodwaters were on the earth. Genesis 7:6

10. This is the genealogy of Shem: Shem was one hundred years old, and begot Arphaxad two years after the flood. Genesis 11:10

Two years after the flood, Shem was 100 years old. Since Noah was 600 years old at the flood, two years after the flood Noah would have been 602. So, Noah must have been 502 when he begot Shem.

Looking at the following verse:

32. And Noah was five hundred years old: And Noah begat Shem, Ham, and Japheth. Genesis 5:32

Noah must have been 500 years old when he had Japheth, his first son.

This agrees with the example concerning Terah and Abram. Terah was 70 when he also had his first son.

26. Now Terah lived seventy years, and begot Abram, Nahor, and Haran. Genesis 11:26

We found in the first question using Genesis 11:32 and 12:4 that Terah was really 130 when he begat Abram.

So, both Genesis 5:32 and Genesis 11:26 indicate the time of birth for the first and oldest child, not some younger child.

Now it is interesting that Genesis 5:32 names Ham before Japheth since Japheth is the oldest:

32. And Noah was five hundred years old: And Noah begat Shem, Ham, and Japheth. Genesis 5:32

Shem is named first because it is through him that Abraham, the Hebrew nation, and the Messiah comes from. But Ham is thought to be named before Japheth since he is younger. There are many other examples of this same order: Jacob, the younger is named before Esau; and Ephraim the younger is named before Manasses. Even Abram is named before his two older brothers, Haran and Nahor and Moses is mentioned before his elder brother Aaron.

The number of years before the flood should not be 1654 years. Since Noah was 600 years old when the flood started, the number of years before the flood are:

There is no way to pin down the actual date for creation. I made an assumption in my chart as I discuss. I used an approximation of a historical date for the building of Solomon's Temple.

I did not want to wade through the inclusive and exclusive reckoning of time found in the later books of the Old Testament of the Bible. There are probably problems too difficult to solve just like what we have in the book of Judges.

If you start counting the years during the time of the Judges, there are just too many years for it to agree with 1 Kings 6:1. The time of the various judges described in the book of Judges must have overlapped. So, there must have been times when there would be more than one judge ruling at a time. And it is assumed that the times are overlapping by many investigators.

So, rather than trying to solve these impossible problems I just used 1 Kings 6:1 and I followed what other people have determined in their own research.

So, I made the assumption for the time of Solomon's Temple to set the beginning of the chart. Then I used Bible Commentary references to locate the other later times and people.
