I found Sophia Kanthack in the 1900 Federal Census for St. Paul, Ramsey County, MN ED 113 Sophia is listed as head of house hold born on July 23, 1856 age at census 43. She is listed as married for 18 years. Born in Germany along with both parents. She came to the USA in 1875. No husband is listed with her in the household. she is a mother of 4 children all of whom are living. They are residing with her in this census. They are: Wafie(hard to read) born Dec 6, 1885 age 14 born in Mn both parents born in Germany Herman born Aug 8, 1887 born in MN both parents born in Germany Eddie born Sept 6, 1890 born in MN both parents born in Germany Louis born May 6, 1892 in MN both parents born in Germany I was unable to locate Sophie in the 1910 census...perhaps the last name was spelt wrong. 1920 Federal Census for St. Paul, Ramsey County, MN ED 69 sheet 4b Sophie Kanthack age 65 widow born in Germany living with her son Louis age 26 single born in MN works as a clerk. Hope this may give you a few good leads. Paula
