My great great grandfather James Joseph Duffy born Monaghan 1832 (Carrickmacross?) arrived North America ~1850, ending up Cobourg Canada, near me in Toronto area. His parents possibly Lawrence/Laurence and Sarah/Sara (Tracy/Lacy/Leary), Looking for leads to other family siblings to my James if any and siblings to his Lawrence (e.g. Patrick a brother or Patrick a father). So many 'James' and 'Patrick' to figure out. thanks
