My name is Carolyn. My fathers name was Robert Mavis. His fathers name was Carl Mavis (Mewes) and his father was William Mewes. I know he was married to Elizabeth Pendleton and had 6 children. My father and all of his immediate family has passed on. I was looking for any information on William Mewes where he was born besides Prussia Germany and any records you might know of or have. What his parents names were? What year they came here from Germany?And if you know why did my fathers, father change the name from Mewes to Mavis and about when.
