I am trying to trace the descendants of Francis Frederick CAMMACK (1828-1879), Doctor of CLinton, Iowa. He had three daughters Clara (1864), Nellie (1864) and Lizzie (1868) as well as a son Frederick Francis Cammack (1876) by his wife Ellen Lorrain GARFIELD. All were born in Wisconsin, apart from the son who was born in Iowa.
Frederick became a teamster for an Oil company. He married Freida R REUTER in 1901 in Milwaukee and had two children Leroy F L CAMMACK (1905-1983) of Wisconsin Rapids and Wallace Cammac (b1910).
Leroy Cammack married Erma or Emma and in 1940 was living in Milwaukee. They had at least one son William CAMMACK.
