My great, great grandfather was Sylvester Rufus Allen (perhaps Rufus Sylvester Allen). He was born in 04 May 1881 in Stem, Granville Co, NC. He died 09 Mar 1914. He married Faith Wilbur Ostrander on 1901 in Portsmouth, VA. William Rufus Allen, who you speak of, according to one post had a son named Rufus Allen but the date of birth is different. I wonder if there's any connection?
My great grandmother spoke of having Indian ancestors in the Allen family. I've heard people speak of your line as being a Native American family by marriage, perhaps I come from your line. I would love to swap information and find further up the Allen line.
Or are there anymore Allen's from North Carolina that have Native American blood mixed in that you know of?
