[oisinh1]

I'm looking for any information on a John Hagan or O'Hagn b.c. 1828 and died 9th Sept 1896 in Tonduff in Desertegny parish. John died unmarried and was listed as a retired Head Constable in the RIC. I've tried searching for an RIC record, but cannot find anything.. so I wonder if anyone could help me to find his service record?

On FindMyPast his surname has been mistranscribed as 'Magar', so you will need to search for that.
