Hi Eveline
Do you know the name of Robert's wife in America? There is this marriage entry in Manhattan:
Hardy Robert C
Date of Marriage: Mar 22 1928 Manhattan
Certificate No. 7293
Bride's name: Perdew Alice G
When searching for births for Robert in Scotland, it is probably worthwhile searching the surname as Hardie as well, a more common variant. There is one entry coming up for births in Aberdeen area for a Robert HARDIE (without initial C for a middle name) between 1883-89:
1888 HARDIE ROBERT M KEMNAY /ABERDEEN 207/00 0029
From the 1891 Census, this Robert's parents look to have been a William (farm servant) and Janet ~ doesn't bode well for a diplomat's family....
I would probably look to America for confirmation of his parents' names (Robert's marriage/death certs) and then work back from there.
Have you looked for Robert and family in any of the earlier American censuses? You might want to put up a new post on the emigrants to the US board here on RootsChat where people with better access to these resources may be able to help:
