The marriage is an IGI contributed record - by "unknown" (usually a LDS Church member), and doesn't appear in the IGI compiled from the church register. Nor in the MM list of Thomas Moore marriages, so anyone looking for it on the parish register film should be told this in case they spend a lot of time searching for something which is probably not there (in Arbory).

However about 8 of their children appear in FamilySearch baptisms, including film scans of the entries. Sometimes additional details such as residence may be given.

If you haven't looked at these please note that it is important to find out everything you can about more recent generations before going to an earlier one.

I haven't read your previous thread, so don't know who you are looking for, but the first child appears to be John bapt German 23 May 1813. All the others were also bapt in German except for one entry (Rushen) where the mother's surname was not given so may have been from a different family. There is also an Elinor bapt German 1819 with mother Elinor Kneal who would fit in with the other bapts.
