I am researching three families the first of which is the
August Fritze family. He was born in Stendal,Sachsen, Germany about 1850. He was married to Fredericka Claudi(or Claude) who was born August 27, 1854 in Barleben,Nuestat, Germany. They had eight children - Otto, Selma, Paul, Richard, William, Alma, Frederick, and Ernest. Trying to find more info on their ancestors.

The second family is the Lewis Stiritz family. Lewis was born in Germany about 1860. His wife Gottlavina Werringer was born in Germany about 1861.They had four children - Fred,Mary Anna Emma,
Freida, and Otto. Trying to find out where Lewis and Gottlavina were born. Also if Lewis had any brothers and/or sisters

The third family is the Christopher Burke Hickey family. He was born in Milford, CT June 21,1892. He was married to Ruth Esther Wheeler born in Milford,CT November 17.1895. They had four children - Walter, Ruth, Anne and Mary Jane. Trying to find
