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.
