Tim, I believe the Pearley Smith who was married to Reuben Allen is my 2nd GGrantAunt. I'm not especially interested in tracking the Allen family, but very interested in any information available about the various places where they lived, and why they moved from one place to another.
As best I can tell, Pearley was born in Litchfield Co., CT. The family then moved to Berkshire Co., MA, and then to Amherst, OH, but Pearley is not listed as one of the family members who made that move. Perhaps she married Reuben in MA?
I also have information about Pearley's ancestry that might interest you.
