Hello Susan,
I didn't see your previous query about Maughold records.
Was the marriage cert you received from the Registry a photocopy of the original entry, or was it a written copy?
I ask because in the Maughold parish register Allan Martin's occupation is given at his marriage as "painter", not janitor.
There are two later marriages where Allan Martin is given as the father:
9 Dec 1883
William Frederick MARTIN Full age Bachelor Fisherman Ramsey, Maughold, [father] Allan Martin, House Painter, and
Emily Jane KEWLEY Full age Spinster Ramsey, Maughold, [father] Robert Kewley, Farmer
12 Feb 1890
Walter MARTIN Full age Bachelor Mariner Ramsey, Maughold, [father] Allan Martin, House Painter, and
Jane EDWARDS Full age Spinster Ramsey, Maughold, [father] Thomas Edwards, Storekeeper
The Martin family were well known in Ramsey.
Sue
