Kim, it looks like I might have helped me more than I helped you. Thank you for the information on my Jane Spangler; I have copied it into my notes so that I will be sure to follow up on this.
I hope that your theory works out. In the absence of the proof for which you are searching, your theory must remain a theory. However, I have noted that the pattern of migration from Pennsylvania to Ohio (and sometimes on to Indiana) seems to have occurred in family groups more often than not. So your theory has some chance of becoming substantiated.

I wonder if anyone can help me topple a "Brick Wall." I am looking for the parents of one of my 2nd great-grandmothers. Her name was Margaret Moyer. She was born on Dec. 2, 1830, according to family records. These family records did not give the location of her birth. She married Stephen Harry in Stark County (Plain Twp) on Sep. 23, 1847. They had a son, my great grandfather, Theodore Finley Harry, on June 26, 1848, and then poor Margaret died about three weeks later on July 8, 1848. I noticed on the 1830 Federal census that there was a George Moyer and family listed on the same page as the James Harry (who was Stephen's father) family, living in Plain Twp, Stark Co. Stephen remarried Harriet Pool(e) and moved to Williams County, Ohio. He died in 1864. He and Harriet are buried in Maple Grove Cemetery,, but Margaret was not buried there, so I am assuming she was buried back in Stark County---perhaps with the rest of the Moyer family? I don't know. I have an image from a marriage book that shows Stephen and Margaret's marriage date--but alas, no parents are listed. Any help at all would be appreciated.
