Hi Martine,
First, thanks for the reminder that there are church records for Kerry on the irishgenealogy site....I always just remember Cork! So, I looked at all the nine children, and only the last five of them have records on the Catholic Parish Registry that show the sponsors too....Of the names that appear, the only Reidys are a Jeremia (twice) and a Maria (once), and given that the two 1838 birthdates for Johanna both have mothers named Mary, it doesn't help! But since one of them is Tralee, and the other one is Ballydinlea (wherever that is), I am going with the first result with Bartholomew and Mary Connor as her parents, for now anyhow. Sometimes when one adds a parent name, other hints pop up on Ancestry to either confirm or deny the relationship.
Regarding the sponsors, isn't it typically NOT a grandparent of the child?? But rather a sibling or perhaps another relative or friend? Interestingly, there are three people with the surname Roche (Honoria, Michael, and Maria) who also appear as sponsors to some of their children. Not certain how they are related, if at all.
Thanks,
Carolyn
