Mary Ann Killeen came to the U.S. from Canada in 1868. She was married to Michael Flavin [Flahaven] in 1879 at 19 years of age. They had 5 children. Michael Flavin was a heavy drinker and died young. Mary Ann left Minnesota and went to Helena, MT and opened a boarding house to support herself and the children.
Leslie McKinney, from the same town in Minnesota, also came to Helena shortly there after and, just by chance, went to her boarding house. She had known him back east and had taught his sister in a little one room school house where she taught before getting married. There was 10 years difference in their ages, and they eventually married on October 19, 1893. She was 32 and he, 22. They had four children: Lucy, George L [Leslie], Leonard, and perhaps a Mary Ann but I can't find her in the records.
Mary Ann and Leslie ran a dairy farm or ranch in Prickly Pear, MT and they furnished the Northern Pacific Railroad and East Helena with milk. Leslie was a very mechanically minded person and had rigged a plumbing system into the house giving them running water and had the dairy running by steam.
At one time, they owned 23 houses in Helena. The houses sold for $2000 and less. The dairy was burned out twice and they lost heavily in buildings and livestock.
Leslie died from a stroke at age 55. Mary Ann made her home in her later years with her daughter, Grace, in Helena. Mary Ann died in her sleep, while visiting overnight, at the home of her son, Leonard, in Helena, MT.
