Richard - have you seen the information posted on www.worldconnect.rootsweb.com by Jennie Anderson and updated 4/9/2005? She doesn't give proof by has the following:
father of William Allen: Richard Allen b. @ 1700 New Kent Col, VA and mother: Ann Freeman b. Sept 17, 1724 Charles Parish, York, VA
she also lists his grandfather as Robert Allen and Great-grandfather as Richard Allen b. @ 1654 England and wife Elizabeth Walker, b. 1665 St Peters Parish, New Kent,VA.
As I say - she doesn't give proof - but seems to have done a lot of seasrching.
There is a lot of interesting information about the Albemarle Barracks on the internet - and how they guarded the Hessian troops captured at Saratoga, NY in 1777, eventually moved to Hagerstown, MD - no remains of the Barracks are left - They were located northwest of downtown Charlottsville, VA - north of Ivy Creek - Apparently from what I read the guards suffered a lot of deprivation - poor clothing and food - and their pay was very uncertain -
Another thinglisted on worldconnect: William had a brother Edmund Allen - b. Nov 13, 1751 in York, VA... so the family evidently moved a good bit -
This is not my family, but I enjoy American History and learned a lot by reading about the Albemarle Barracks -
