Addition to my previous post. I know I've seen the same data you have on Jerusha's marriage and child with John Shanks, but it doesn't add up.
Jerusha's dau/of JQA freeland was born 1865 in Louisiana.
According to burial records at the Shank Cemetery, the Jerusha and John that had Ada were:
Jerusha Jane Shanks
b October 12, 1849
d July 24, 1957
b January 8, 1849
d February 20,1924
I can't find anything to back up that either the census records really blew up on Jerusha's year of birth, or the burial record being 16 years off; which would lead to a possibility of them being the same Jerusha.
Please advise if you have something that clarifies any of this. Thanks.
