Thanks for your reply. I've discovered much more about the O'Mearas since posting that message. I was at first confused by your referenced to Mary E. O'Meara married to William Riley Vivian. I had her name as Elizabeth. She did have a sister Mary Elliene. I have Elizabeth Vivian's death as May 21, 1922, but have not located an actual death record online. Neither have I found a death record for Ellen McDonald O'Meara Carrigan, other than the cemetery listing in Dimmit County.
My connection to the O'Mearas is thru my wife. Her grandfather was Milton Hays O'Meara, son of John Edward O'Meara Jr.
I would guess you'd need to go to Ireland to find that marriage record. I'd love to know where in Ireland they came from. Haven't come across a naturalization record for either Annie or Michael O'Meara that might give that information.
