I have Jenkins in my line, although i haven;t done alot with them yet.
But a colleague of mines is a Jenkins and lives in Coatbridge - he belongs the Lanarkshire area. But he is also a monumental mason in that area.
If you know names and are looking for graves - you could try contacting North lanarkshire council on e-mail: email@example.com
If you have any luck getting lair details i'll see if i can have a look into them for you.
