I have found him on the 1901 census in Leck, Letterkenny and I think I have found him in Scotland in 1911. Since posting my query I subsequently found his first marriage in 1933 to an Elizabeth McGurk in Scotland but now have to find out where he was between 1911 and 1933.
I was born in scotland but my parents moved to Northern Ireland and live in country tyrone approx. 30 miles from Letterkenny believe it or not.
My research has indicated alot of clothes dealers/tin smiths etc in my O`Hanlon line but to be honest they all appear to be related to each other. Would be interested to know the names you are researching?
