I have cousins who I know are cousins, but we can't find a documented link. We think my cousin's grandfather and my grandmother were first cousins. I found my relatives in Ireland and they think so too, but don't know for sure and can't prove it. I got Thomas Boyle's death certificate but his son put a question mark under parents' names.I have his naturalization record, but nothing and Philadelphia did not send me first papers. He wouldn't have had social security. He was born in Ireland approximately 1842 and he died in 1924 in New Jersey. Would he have written his parents names on any document I could try to order? Thanks for any ideas. Winnie in Vt.
