I am looking for info on my husband's grandpa. The grandpa's name is he believes is Claude Jack Moore who married Mary Blakely. mary passed away in 1993.

I would appreciate any info you can provide.
Thank you.

I am looking for dates for some of my ancestors that I am stuck at.

David Joyner (born)1808 SC,USA (Died)1870 Mississippi,USA
(Married to)Rachel Leigh Jenkins (born)1819 SC,USA (Died)? in Lee,Mississippi,USA
(children) 9
Emily Joyner
Joel Joyner
George Joyner
James Knox Polk Joyner
Elizabeth Joyner
Martha Joyner
Sarah Joyner
Walker Joyner
David Fletcher Joyner
(I have the dates for the children if anyone is interested)

I am looking for David's parents names and info.
I have a few on Rachel's side, but I am stuck at her GG-grandmother and Rachel's mother.

If anyone can shed some light on my problem I sure will appreciate it and I will try to share what I have.

Margaret Helderman was my GGG-grandma and I cannot find her on familysearch.com. So therefore I believe that the info I got from ancestry.com from another members tree may be wrong.

Here's what I have:

Margaret Helderman
B: 1824 Missouri City, Fort Bend, Texas, United States
D: 1862 Missouri, Brown, Illinois, United States

Is there anyone who knows of any Heldermans from Texas that can give me the names and dates for her parents?

Thank you.

P.S., She married Joel Nance in 1844.

My Dad was told when he was younger that an ancestor of ours by the surname of Nance was Sitting Bull's Grandpa. I find this hard to believe and am only trying to prove or disprove it. It would be an honor, though, if such a great man were related to me.

Does anyone have any info they could share?
Thank you.
