New to Ancestry and found your post. I am a decendant of George Ermatinger Jr. I do not believed that George Ermatinger Sr was ever married to Mary MacDonell as we have never located a marriage certificate. I do have a census record for George Jr. and his family and it shows that Mary MacDonell was living with him and identified as Mary MacDonell. I never have found an acknowledgement by George Sr of George Jr but it appears that George Jr had contact with George Sr's children by McKee.
