Hi Alex,
He testified on Sep 3, 1658 as to his age (42) and birthplace (England). He was named after his English father, Christopher Davis. Having a Dutch mother, it isn't hard to imagine why you'd find his name recorded in the Dutch version of it; not to mention that he lived and married among the Dutch.
I suppose that it is safe to say he was born in England. As safe as to say I was born in Tacoma. [I was, you can take my word for it. ;-)]
I noticed this before, sorry I didn't change it then. Thanks for bringing it up. It needs correcting.
