Sorry, I forgot to put the birth years but it seems people have found them from the 1881 census, 1854 and 1855 respectively.
I know that Herbert, son of F.A. Vincent (Headmaster of Batley, then St. Chad's in Staffordshire and a couple of other churches), went to New Zealand, following his brother, Frederick Janvrin Vincent, and FJV then went off to USA. It seems, due to existing in the 1881 census in Croydon, that they returned and Herbert Frederick Janvrin Vincent was born at sea on the way back. However, post 1891 I cannot find him. His brother and HJV's sons are very much in existence and I have details for them. Just wondering what happened to Herbert Janvrin Vincent and his wife.
Thanks for the help.
