Re: GUILFORD CO., NC - MACY, ANGEL, KNIGHT
Have you checked the Encyclopedia of American Quaker Genealogy? There you will find a Macy family in NC and follow them to Indiana. I believe these Macys were in the contingent that left NC because of slavery.
I did some work on the Solomon Macy family because one of the children in that family, Samuel, married my great-grandmother Mary Ann Kirk Briggs after her first husband William Briggs died. They subsequently had three more children.
I will be glad to work with you on this, if it appears that it might be a link.
