I have a ggg grandfather Moses Nowlan who married a Margaret Rossiter around 1807 we have not found a marriage record. However, we have baptismal records at the Cathedral in Enniscorthy for 8 children born between 1808 and 1822. The youngest child Ellen b. 11-20-1843 married a Miles Rossiter at St. David's 2-14-1843. We also have record of one child from this marriage of an Elizabeth Rossiter b. 11-20-1843. Does this fit in with your group at all?
