Many thanks to June who sent me updates on this line.
I have now found the marriage certificate for Edith Rebecca Buer to Frank d'Harty in Yokohama, Japan in 1901.
I understand that they had a son, Frank and as yet I have not found him, but I'm still looking.
I would love to hear from anyone researching this family, Henry Wells Buer and Dinah Alice Butcher who married in 1867 in Croydon, Surrey. My great grandmother, the above Edith Rebecca Buer was the 4th female out of seven children altogether.
Kind Regards,
