This is a very old message, but I will try to answer. Ellen Flynn was born in Ireland in 1836, and immigrated at an early age. I don't know much about her 1st spouse, but daughter Susan was supposedly born in St. Louis in 1860. I am guessing a soldier husband. When she married Patrick Kelly 25 March 1873, she actually had 3 daughters, Mary (1858) Susan, (1860) and Ellen (Nellie) 1869. There may have also been a son John (1858) but this is unclear as he only appears with Nellie Kelly in the 1880 Census at Ft. Abraham Lincoln, Dakota, where the 7th Cavalry rode out of to Little Big Horn. They are living with Susan Flynn Kelly White Pitts, married to Major James Garvin Pitts, the Trader at the Fort. He was originally the trader at Ft. Rice when he married Susan, a 16 year old widow!
Mary Flynn, married UNK Carey, and died in Bismarck, ND 1884. The oibit seems to indicate her husband was in the Army as a drum major?
Nellie married an Army officer, James Purcell (1865-1938); they both died in San Francisco, CA. Nellie on 07 March 1938; possibly 5 children.
Ellen Flynn Kelly moved to Bismarck after 1876, where the girls grew up. She operated a restaurant for many years, Mrs. P. Kelly's. In 1884, Susan and Major Pitts moved to Winona, Dakota Territory, where he became the Trader for H.D. Douglas in a Dry Goods Store, and Postmaster. Ellen opened the Morningside Cafe in Winona.
Susan Pitts died in Winona of Bright's Disease (kidney failure) inOctober 09,1891, leaving three children, Alma E. (1878-1904)), George Alexander (1880) Chester A. (1883) and Irene Ellen (1885-1975).
Ellen Flynn Kelly died in Winona, ND at age 63; (reported 26 February, 1899.) She was buried at St. Mary's Cemetery in Bismarck. Obit lists Miss Alma Pitts, wife of Sergeant Havelick, service in Cuba.
During Ellen's stint as a restaurant owner, she was indicted and arrested in 1891,for selling illegal liquor to Indians from Standing Rock Reservation, Sitting Bull's home, but usually ending up paying stiff fines. I found a complaint letter in 1898, in the National Archives, to the Indian Agent at Standing Rock, so she was still doing it seven years later. To be fair, prohibition was in effect in ND, and Winona had 8-9 illegal "blind pigs" at the time, so indictment and arrest were not uncommon. Incidently, it was my great-g-father, Jack Waldron, an Emmons County Deputy Sheriff, who arrested her the first time, despite the fact, that her son-in-law, Major Pitts was a good friend.
Anyway, hope this is helpful.
