I was researching Leavitt Beal Keeling and came across your message.I was at a dead end with Leavitt as there was no information on his parents except on a few census's that said his father was from England and his mother was from Wales.It also stated that Leavitt was a veteran, possibly civil or Dakota Indian wars. (age young for civil, but you never know with ages.)
The information that you have on his birth and death seem to be correct from the information I have gathered.Leavitt was a bricklayer or brickmaker for SC Brick & Tile works on Correctionville Road in Sioux City, South Dakota.He married Mary Elizabeth Ross, born in 1856 in Iowa.There is not much information on her, except that there is a picture of her in the Evans family tree on Ancestry.com.I will have it later as I just looked at it today and I havn't doownloaded it yet.She was listed on the 1910 census as alive and living in Clay, South Dakota with Leavitt.Leavitt is listed on the 1930 Census as a widow, but living in McCone, Montana as a justice of the peace.I'm assuming Mary Elizaeth died between 1910-1929.Leavitt possibly may have married again to a Mary Watson, born in 1857 in Indiana.She died in Montana as well, so I think there is some connection there.I cannot verify much information with Mary Watson, as there is not much on line about her.
Leavitt and Mary had 6 children, Ross, Elmer, Olive, Wilfred, LLoyd and and Edith.I have their ages from one of the census' if you need them.Edith is my great grandmother on my maternal side.Edith was born 5 May 1887 in Sioux City, Iowa and she died on 1 Aug, 1956 in Brookings, South Dakota.She married Archibald Adington McMillan, b. 16 July 1880 in Mount Forest, Ontario.They married in 1909 in Sioux City.He died on 10 April, 1977 in Reno, Nevada.
I hope this helps if you don't have the information yet as your message is from 2 years ago.If you have any updated information on James Keeling and Jane Lloyd, let me know as they are my next research.
