Hi Diane,
I've been a bit slow in replying (7 years).
My grandfather was Hellier, born in Australia, her was the son of James, born in Guernsey in 1860.
My father, Helliers son tells me that there was a tradition of naming the first born son Hellier.
My great grandfather James was born in a house called La Fontenelle (not to be confused with the town at the northern end of the island). The house is located in St Pierre du Bois.
I have collect some info on James but only a little. whether he is a descendant of your Hellier I cannot tell.The surname was somewhat common I understand but I don't know how common.
I guess all LeLacheurs from the Channel Islands are related but the connections may predate the oldest records.
I have just read Marie-Louise Backhurst book on Tracing CI ancestors and intend to use it to find out more information.
I look forward to your reply
Gary LeLacheur
