Thank you very much for clarifying that. I hadn't realised that the maps were made in 1839.
I had a look at baptisms with sponsor Martin Kelly.
1. The first one was with Mary Kelly for Maragret Egan born in 1819 in Eden to Michael Egan and Bridget Dillon. This is before the time of my ancestor. Interestingly, I had thought originally that my ancestor Martin was born in 1819 in Eden to Martin Kelly and Jane Dillon. However, someone who is supposed to be descended from this couple did Y-DNA testing and our last ancestor lived around the 1200s.
2. After that (in the relevant time frame), it's Martin Kelly (transcribed Kenny) born to Patrick Kelly and Catherine Frihill in 1852 and the other sponsor is Mary Kelly. This appears to be Patrick's oldest child. Patrick gave the eldest the name Martin while Martin gave his eldest the name Patrick. Perhaps they named their eldest after their brother rather than father?
3. Then the next baptism is for Patrick and Catherine's son John born in 1854 with the other sponsor recorded as Mary Freehil.
4. Martin Kelly and Mary Finan were sponsors for Mary Freehil born to Terrance Freehil and Bridget Finan in 1856. Therefore, Terrance was likely a brother of Mary Freehil.
5. Martin Kelly and Bridget Freehill were sponsors for Catherine Kelly daughter of Patrick Kelly and Catherine Frehill in 1859.
6. The last is Martin Kelly and Jane Dockrey acting as sponsors for Peter Egan born to John Egan and Mary Kelly,
There's nothing new there except Terrance possibly being a brother to Mary. Martin Kelly and Bridget Kelly were also the witnesses for the marriage of Terrance Freehil and Bridget Finan in 1851.
However, I also searched Patrick as a sponsor. As well as being a sponsor for Martin's children, he is also a sponsor for Terrance Freehill born to James Freehill and Mary Kelly in 1852 and again in 1856 for Margaret born to the same couple. Perhaps he's a sponsor because he's a brother-in-law to James rather than a brother to Mary since there's already a Mary who married Egan?
The first record of a son born to John Egan and Mary Kelly was named Peter in 1861.
I looked up Patt Egan but all that I could find was more voter lists. His name appears along with Edmond Cregg of Cloonsheever in 1835 as applying to be registered as voters with both recorded as freeholders. Another list on 5 october 1844 to be registered as voters were Patt Egan along with Patt Carty of Cloonsheever (farmer freeholder), Thomas Cregg of Cloonsheever (farmer freeholder), Peter dockery of Cloonsheever (farmer freeholder), Terence Feehil (farmer landholder), Thomas Feehil (farmer landholder), Dudley Mulrenan of Cloonsheever (farmer landholder), and Michael Surrage of Cloonsheever (farmer freeholder). On 14 June 1834, Patt Egan (farmer) was also applying to register to vote.
I have a query about the voter list that I've attached. The list is styled (number)-(name) but at 236 it becomes (number)...(name). I noticed this on another list. The alphabetical order also restarts for a different set of names with 316...Kelly, Andrew, Toberory, farmer, leaseholder towards the end of the list. I don't suppose you know why some would have been organised separately alphabetically. Andrew was likely genuinely able to vote. He owned 151 acres and previously owned all 571 acres in Toberory. His father lost his total land holding since he wouldn't conform. William French of Cloonyquin took over the esatate and after negotiation his father agreed to be a tenant and was given the 151 acres.
Once again, thank you for your help. You're always a helpful bunch here!
