Hi Kathleen,
Sorry for not replying sooner, I haven't been on Rootschat for a while. Do you have any dates (Birth, Marriage) for your grandfather? As you'll see from this thread, my ancestors left Dundee around 1866 so if we are related, the link would probably be a couple of generations further back from your grandfather.
Let me know what information you have and I'll see what I can find.
Regards,
Al
ps I made a breakthrough this week on locating my ancestors in France! The 10 year BMD indexes for the North of France have just become available on line and I managed to find the birth records for two of my G Grandmother's brothers. These indexes are for a specific town so I'm owrking my way out from Dunkirk town by town to see what else I can find.
