Hello Bernadine,
I have some records of the gravestones in Termonfeckin for you I'm not sure if they will be of use.
Brodigan IHS Erected A.D 1840 by John Brodigan of Baltray to the memory of his father and mother & posterity (grave No 167)
Brodigan Erected by Mr Anthony Brodigan of Termonfeckin in memory of his wife Mary who died 14th December 1851 in the 28th year of her age and his daughter Cathrine who died on 6 December 1863 aged 18 years. Also his son Peter John who died July 2nd 1864 aged 65 years requisent in pace, Cecilia Carron died 26 Dec 1940 (grave No 407)
Brodigan IHS Erected by Mary Brodigan of Termonfeckin in memory of her beloved husband John Brodigan who died Feb 19th 1881 aged 53 years and their children who died young Michael and Christopher. Jack Carton died Sep 1967 aged 63yrs. His wife Nancey died 29th June 1987 aged 80 years. May they rest in peace ( grave no 168)
Brodigan In Loving Memory of Thomas Brodigan Port who died 21st Feb. 1969 and his brother John died 29th Jan 1958 R.I.P (grave No 166)
There is also records of Brodigans being shop owners in the town of Drogheda just 5 miles away, and members of the Drogheda Corporation. They lived on West Street Drogheda, I also believe they might have been Brewers during the mid 19thC.
I'm not sure if this is any help to you, if I come across anything else I will let you know,
Kind regards
Historical
P.S Baltray is a sleepy little hamlet by the sea just about a mile from Termonfeckin, people from baltray would be buried in Termonfeckin, I suggest you try with the parish records for St Peters Catholic church Drogheda and the Diocese of Armagh which will include all records in Termonfeckin..... Good Luck
