Today I learned that proper citations are our friends. I found on Roots Web a nice transcription of a family Bible that includes one of my ancestors birthdays. That with a couple of census records verify at least the month and the year.
Unfortunately, no other information about the source was included other than it was the George Washington Webb & Elizabeth Gant family Bible. I tried to email the original poster but since the message was from 1999 it was unsurprisingly returned. I have contacted a few distant cousins who are also working on this line in hopes that they have a little more information on this source.
And I thought the first assignment in the NGS Home Study Course would be a cinch.
Now I'm just repeating to myself, "cite your sources, cite your sources" until it sticks.
