I have a teeny bit of info on Louisa's husband, David.
Louisa Richards Ingram [b. 2/24/1863, Shullsburg, WI; d. 12/11/1939] was the sister of my great-great grandmother, Jane Richards Copeland of Shullsburg, WI.Louisa was married twice.She married David Ingram [d. 1898?] and they had two children.(Louisa was also married to a John Bilkey, who is buried in Dodgeville WI.No children.)
David and Louisa's first child was 1) Gladys Ingram [b. 07/25-26/1893] who married George Sanger [d. 1/24/1946].They had no children.Gladys and George are known to have lived in Chicago in the 1940's (my Dad stayed with them on a childhood visit there).
David and Louisa's second child was 2) Marie E. Ingram [b. 1/31/1895, d. 9/15/1964].She was a school teacher in Milwaukee, WI and a member of the Dodgeville Methodist Church.She is buried at the Eastside Cemetary in Dodgeville, WI.She never married but was excellent with kids.
Louisa was a student at the time of the 1880 US Census and lived with her sister Jane and family in Shullsburg.
Another sister, Eliza Emily Richards(Aunt Lidy, b. 1/13/1859; d. 11/28/1935, a dressmaker) married a Thomas Kneebone 11/8/1883 then later married Tom Ingram, who died 11/5/1924 at Hancock, MI.There were no children from either marriage.I'm guessing that Tom Ingram was a brother of David Ingram.
That's all I have on the Ingram line.I hope it helps you.
