Thanks for that, feel we are getting nearer, unfortunately we haven't letters or conneections that might help, only the photograph, it looks as if the boy you found Thorvald William is probably the youngest of the three we are looking for, he was obviously born in the same parish as the two girls, the other two boys I would say look around about 15 and thirteen years old which would put their birth years to approx. 1883/4 and 1885/6, it,s so difficult, when Hilda was born in 1913, children were meant to be seen and not heard, so she knew very little of the Danish family. Thanks for all the help.
