Hi Osprey, thanks for such a quick response, so that's 2 of us with connections in Heligoland!
Hi Berlin Bob, thanks for yours also, can I please draw on your vast experience and ask this.... Gt Grandad left Heligoland about 1880, I have his Marr Cert of 1892 stating Born Germany, British Subject. Would that be because married a Brit or was it because of the history of Heli.... Cheers, Johnnie
