Harm Heinrich Grashoff

I have been attempting to "digitize" my documents and in so doing I was rereading some of the information that I recieved from the church records in Germany about Harm Heinrich Grashoff. What do you know! The record of Harm's wedding to Elizabeth Massemann states that he is a widow. That would mean another wife and possibly other children somewhere. So, the suggestion of revisiting all information is always a good one.
