I am looking also for a Martin Tierney who married Elizabeth A. Doyle who lived on PEI during the 1800's. They married at St. Jeans Immaculate Conception Cathedral in 1880 and had at least 3 children in the area of St. John, New Brunswick, Canada. By 1866 or so, they appeared in the State of Washington, Thurston County (Martin first, later followed by Elizabeth and children. They are listed on the Washington State Territorial Census (approx. 1885-86). They resided there until their deaths. I have a group picture of Martin and four of five of their children. This Martin was born or baptised approximately October 15, 1855, but I have also seen 1857 and 1859 as possible years for birth as well.
