I am looking for information about a Katherine Sojka who was born in Poland, she put Poland/Germany in several U.S. censuses and Prussia in the earlier ones. She was born in 1840, immigrated around 1868 to the U.S. and died in Shawano, Wisconsin in 1911, and was married to Andreas Strelke. I was curious if these two women could have been sisters. I have no information on her parents. She is my husband's great-grandmother. Thanks, Susan Hancock
