I'd be interested in seeing some of your work on the Irish Luddens. Anything on the Chicago contingent?
My grandmother was Alice Ludden (Gorham), born around the turn of the century, her sister's name was Katherine Ludden (McCarthy). I don't know much about any other siblings. Both were American born. Both married at St. Bartholomew's Catholic Church in Chicago. My great-grandparents were Thomas Ludden and Mary McConnell. I believe they were were directly from Ireland.
His parents were Thomas Ludden and Katherine Fitzgerald. Any fits with the work you're doing?
I'm running into similar issues with the Gorham name in America. Lots of English lines. Lots of dead ends...
