My Great Great Great Grandmother was Judith Neal. She Married Charles Byrne and their first child (or so I believe it was their first) Was my GGGrandfather Danile Byrne who was baptised in Avoca, County Wicklow in 1823. This would put Judith in the same generation as your ancestor...but I don't know of any of Judith's siblings or whether or not she is related to your ancestor. Have you ever heard of a Judith Neal in your search ?
Thanks, Tommy Byrne
