Hi I know my great grandparents were from Newfoundland. I know they had 13 children. Known of those listed by you sound familiar. Neither do the twins. Then again what I do know is a couple names are Margaret ,Helen (Ellen) John (jack), he lives in maryland now. Geri, Bud, Patrick, Micheal, Dot, Gus Elizabeth.
If any of this sounds familiar let me know. I do know most of them have lived or died near New Jersey and Maryland.
