Hi,
I dont know how it works in Jersey,my family on the maternal line go back to 1600,s in Guernsey,but for others searching the channel islands this may help,my ggggrandfather was born in Suffolk,so how come I ended up with family from Guernsey,answer,he was in the army and stationed at Fort George Guernsey,some of the children were born in suffolk,someone from the Priaux library was brilliant,(Margaret) she found my GGgrandmothers registration,under Mayo instead of Mays,they were really helpful.
