hmmm well as a member of the UC I would say that UC and Anglican are pretty much similar in most of their beliefs - ie both protestant Anglo-Saxon roots - so I can't see why either wouldn't accept the other's baptism.

I was baptised UC and the Catholic Church accepted this as proof of my christianity to be allowed to be wed in DH's church. I really think you should talk to your minister first before you get too worked up over it.
