SENNETT/SINNOTT - several siblings who left Wicklow (possibly Rathdrum area) for West Yorkshire in about 1843-1848, including Joseph (b abt 1817-21) and wife Julia Ann nee RYAN, Edward (b about 1819), George, b about 1820.
Others who left Wicklow for W Yorkshire, and later married into the SENNETT families, including FARRAR, DOYLE, KEARNS/CAIRNS, KENNY/KEANEY/KANEY
RYAN - Julia Ann, b about 1820, and brother John, and father probably John.
While I have a lot of information about these families once they arrived in West Yorkshire (mostly to work in the coal mines), I have yet to confirm exactly where they came from in Ireland. Census usually gives Co Wicklow, and family stories say Wicklow or Dublin, with one branch of the family believing they originated in Rathdrum.
