Hi Jim,
Here is what I have in my tree for the Stronners.
My 4x great-grandmother is Elis(z)abeth Stronner b.1792 Inverkeilor.
She was the daughter of William Stronner and Agnes Fin(d)lay.
They also had the following children;
John b. 1784
Jean b. 1787 d. in infancy bef. 1790
William b. 1788
Jean b. 1790
Helen b. 1795
All were born Inverkeilor.
Their father William was the son of (I think) another William Stronner. No info on their mother.
Here are William Jr's siblings;
James b. 1751
David b. 1753
Elisabeth b. 1755
Robert b. 1763
All born Inverkeilor again.
Potentially more children between Elisabeth and Robert (other than William) but don't appear to be registered.
As you can see most of my Stronner research is further back than what you have I will have to descend further down and see what I can find through the various male lines to see if I can get a match to any of yours.
Does anything there match with anything you have Jim? I'm not sure how far back you've gone with the Stronners. We could have a potential common ancestor if I finish off my branches.
Regards,
Jill.
EDIT:
John Stronner was the son of David Stronner (1810-1886) and Susan Robert (1816-1883).
I've done a search for all the David Stronner or Stroner 's born/baptised in Scotland between 1805 and 1815 and there are only two come up;
One baptised 1814 in Liff, Benvie & Invergowrie. Father David Stronner
the other baptised in Inverkeilor 1812. Parents; William Stronner and Jean Morris.
Could your David (1810-1886) be the 1812 David Stronner b. Inverkeilor?
I have a William Stronner b.1788 in Inverkeilor. This would fit with ages and could potentially be a match for your David's father?
Let me know your thoughts.
Thanks again,
Jill.
