Thanks.
I had assumed that maybe Robert Wallace was named after a Robert McGimpsey but wasn't sure. Since posting this, I found this which has been a bit helpful:
http://geyer-genealogy.blogspot.com/search/label/McGimpsey It seems all McGimpseys may be related?
I thought I posed some of this but must have deleted some of it by accident before making my first post.
I have been looking into the McGimpseys a bit before I found out my 4th great-grandmothers maiden name was McGimpsey. I had forgotten to add that to my post. My granduncle Andrew Lowry Brown (Grandson of Hugh Brown and Agnes Wallace) wife was Mary Elizabeth McGimpsey from Drumawhey and her aunt or great aunt was Margaret McGimpsey was wife to my 2nd Cousin x4 removed, James Rankin of Crossnamuckley:

I also have a 1st Cousin x4 removed, James Shanks from Ballyfounder, Portaferry who's wife was Susanna McGimpsey from Drumhirk, Newtownards, father Thomas McGimpsey a blacksmith:

https://civilrecords.irishgenealogy.ie/churchrecords/images/marriage_returns/marriages_1855/09497/5441956.pdfAt Hugh Wallace and Margaret's daughter Sarah Wallace marriage to Patrick Adams, a Sarah Ann McGimpsey was present:

http://www.newtownardshistory.co.uk/family-mc-gimpsey.htmThere is also Hugh Wallace and Margarets daughter, Margaret Wallace who married James McWhinney from Whitespots. Their daughter Margaret married a John McGimpsey a blacksmith who was living in Kirkdale, Liverpool at the time of marriage and his father was Robert McGimpsey, a blacksmith:

I just had a look for Loughriescouse McGimpsey and while I am not sure if this is him, I found a Robert McGimpsey:
