Hi Weechaz,
I have approx 70 Lowes in my tree,42 of which are from Stranraer.
I also have 40 Allisons,again from Stranraer.
The wife and I reckon the guy in the middle of your photo is a Lowe as he has a striking resemblance to her father.
Unfortunately,the father in law lost contact with the Stranraer side of the family when his father died in 1963 and the last record for an Allison that I have is a death in 1946.
Keep posting Weechaz then if you want we can PM.
Regards
Brian
