I should really check this more often.
Bridget Davin married a Michael O'Brien. Most likely in Waterford. I do not have names of parents but I have a note about a "Davin from Deerpark". They had at least two children, maybe more. James S. O'Brien (b. 1905, Waterford) moved to Chicago in the mid-20s and married an O'Sullivan from Youghal.
