Gladys55 on Family Tree Circles

I have the Bernhagen family from 1782 - 1940 What I don't know is did the name spelling change to Purrenhagen. Or, is the name still Bernhagen and there are not anymore more records to be found. Martin was born in 1782 and died in 1842. He was married to Henriette Lavisa Lemkens born in 1787 and died in 1868. They were married on 11/15/1808 Deutschland. So, am I done with this family line or does someone have a new start for me?
