Hi, many thanks for your very interesting email.
Unfortunately, I cannot tell you the relationships between the 5 Aghagegna households. In my researcher's report, she suggests that my gggrandfather John 39, George 36, and William 33 were brothers and that William 70 was their father. Each of the 3 "brothers" named their eldest son William. She states that the practice of naming the eldest son after the paternal grandfather was extremely common and can very often be a good guide when other links are missing. I can only assume that she thought that Richard 66 was the father of Richard 22 so William 14 would not be the elder Richard's eldest son.
My report shows that the sponsors at John's son William's baptism on 31/01/1808 were Richard & William Stephens. I wonder if they were John's uncle & father? It seems a great coincidence that Richard's son William was baptized on the same day - do you have the names of the sponsors at that baptism? It would seem quite a possibility that the 2 William's christened on the same day were 1st cousins. Were they at the same church?
Another interesting item in your email , is the marriage of your gggrandfather William to Sarah Hanna on 3/6/1830 - one of the witnesses being John Stephens (my gggrandfather?). My report mentions a marriage on 23/7/ 1836 between Susan/Susanagh Stephens & James Hanna. Witnesses were William Stephens ( her brother, uncle or grandfather?) & Henry Telford (sic). The fact that the 1st child to the marriage was christened Isabella suggests that Susan was my gggrandparents John & Isabella's daughter. This thought is reinforced by the fact that one of the sponsors at Susan's baptism on 2/2/1812 was a Susan Trelford (sic).
My report revealed that there had been several marriages over the years between my paternal grandparents' families, ie. the Stephens and Bell's. It could be the same between the Stephens and Hanna's?
You say that your William was born 1807 in Portan? and baptized 31/1/1808 (at Kildrumferton?) . I cannot find any mention of a townland called Portan. Is it Portruan ( near Belturbet)? If so, this is strange as my grandmother's family, the Bell's, lived in Drumalure Moor (ie. Drumaloor) near Belturbet.
Have you come across any Bell's in your researches? Have you done your own research? Best wishes, Mike
