Surnames
Bagley, Baguley, Bigalow, Bigelow, Biggalough, Biglo
Background
The male Y-chromosome is passed on, father to son, mostly unchanged through the generations. Because of this, the markers on a male's Y-DNA correlate with his patrilineal lineage and surname.
Some surnames are found to consist of just one genetic line. Others have few or many distinct genetic lines that are unrelated but share the same surname for a variety of reasons.
The best modern genealogical research incorporates both genetic and documentary sources. The accessibility and affordability of DNA testing is doubtless the greatest technical advance in the history of genealogical research because - at long last - we have a tool to break down those brick walls and confirm or refute long held stories where the documentary evidence falls short.
You can find the primary online source of documentary information on the Bigelow surname as it relates to the Massachusetts immigrant John Biglo at the
Bigelow Society website.
Important reference is made to an African-American Bigelow family at the
Caswell County [North Carolina] Historical Association website. (See additional information under Results.)
