Most of the surviving early manumissions were on the Eastern Shore and are
recorded in Douglas Deal's _Race and Class_. I don't recall anything about
baptism in their manumissions.
Michael Gowen (1657) and Philip Gowen (1675) were probably Christians when
they were freed in the York County area. A "Mulata named Emanuel" was
adjudged to be a Christian servant by the Virginia Assembly in September
1644. He was ordered to serve as other Christian servants and freed in
September 1665. He was probably identical to Emanuell Cambo (Cumbo),
"Negro," who patented 50 acres in James City County in 1667.
John Kecatan/ Tann was freed in Charles City County about 1665. He was
probably a Christian, but that did not apparently figure in his manumission.
Tony Bowze (Bowser) "Negro" was granted his freedom in 1676 on his payment
of 800 pounds of tobacco yearly. John Archer bound his son Thomas as an
apprentice in Northampton County in 1697, but nothing was said about how
John became free.
