Hello There
It is good to hear from the cowie side as I know no one from my fathers family.
This has been a year of study so not really focused on family history. I have come unstuck at the same place as you. I live in Scalloway on the west of Shetland. We did see a lady called Jess Bruce when I was small and my dad who is now 79 was in touch with Patsy Bruce.
I know my grandfather had brothers, Albert and David. Donald fell from a ship and died when he was 18.
I think Patsy had a daughter called Pat.
It would be good to have some more information.
Look forward to hear from you and sorry for the late reply

Mary
