California Settlers Genealogy Reference GENERATIONS About/Contact
Generation numbers on family trees here are in two formats.
1. Moving back from the generation born around 2000 which is generation 1. 2. Moving forward from the first American immigrant. So generation 1 moving back would be generation 15 moving forward for people related to the Thomas family.

The families represented here are centered around the California settlers and the first generation born in California (generation 6 - Lewis Leroy King & Annie Hellar, Thomas McBride & Emma Finley, Jonathan Sikes & Caroline Woodley Palmer, Benton Thomas & Susan Guard..., all the authors Great Grandparents).

Birthdates by Generation

Note: The count of immigrants above is for ancestors of the 8 family lines in generation 6. e.g. the 30 Sikes immigrants listed between 1600 and 1649 are 30 of the 128 generation 13 G-G-G-G-G Grandparents of Jonathan Sikes, only one of which (Richard) was a Sikes. We have identified only 33% of the immigrant ancestors of 8 families here so there are a lot more than those shown. The later a family arrived the fewer entries they have in the immigrant list. e.g. Thomas McBride, the generation 6 ancestor we started with, was an immigrant himself (Scotland to Canada in 1851 and to Calif in 1870), so there are no other McBrides in prior generations.

See Builder, Boomer, X, Y below.

Because women tended to get married earlier, maternal lines have more generations in a given time. e.g. Anna Price (an ancestor following a purely maternal line) was born in 1750 and is generation 10; Thomas McBride (a paternal line) was born in 1749 and is generation 8.
Also the age differences between the youngest and oldest children, which can be 15 years or more in the 18th and 19th centuries adds up over several generations. e.g. James Finley (b. 1783) is generation 8 when going back thru the Arthur Thomas McBride (children born 1905-15) line but generation 7 when going back thru the Shadrach Gladney (children born 1899-1905) line.

Each generation averaged from 32-42 yrs. up to Noah.
Generations from Adam to Noah were several hundred years according to the Bible. Because your number of ancestors doubles each generation (2 parents, 4 grandparents, 8 great grandparents), after about 30 generations (1000 AD) the number of a persons ancestors exceeds the world population. The fallacy in this argument is that prior to 100 years ago a lot of people married 2nd and 3rd cousins, so lines tend to merge quickly as you move back.

Generations Numbers on Ancestry Pages Here | Top

There are two numbering systems used on the ancestry pages here.
1. Generations starting with the first immigrants moving forward in time. We assigned these to match up with published genealogies. These vary from family to family because of the different dates of immigration.
2. Generations moving back in time from about 2000; (Children born at the beginning of 2000 are in the middle of generation 1 and the beginning of generation 0.) This makes the settlers and the first generation born in California Generation 6.

Generation 6 ancestors were born between 1839-1863. Their average family spanned 20+ years (from youngest to oldest child). We centered the genealogies here around this generation, so the generation boundaries spread out as you move forward and backward from generation 6. For example the median birth-date for generation 2 is 1971 which is Gen X, however there are about 200 generation 2 descendants of these California Settlers with birthdates from 1949 to 1998. The median birthdate for generation 3 (the Great Grandchildren of the settlers) is 1945 which is on the builder/boomer boarder line. Generation 3 birthdates range from 1922 - 1970, so some spill into Gen-X.

* The high number of Scottish ancestors is a result of Thomas McBride comming fairly recently, so all his ancestors (even though we can only identify 4 past generation 8) are assumed to be Scottisn (Note: DNA studies show many may be Irish). We probably have many more English, Irish, German and Duch ancestors, but have run into dead ends in the US so don't know the country of origin for many who have been in the US longer.
