I have run into a brick wall with Joseph Kirby christened 8 Jul 1821 in Helmsley (son of Stephen Kirby and Cordelia Garton) and his wife Christiana Allenby or Allanby, born in Pockley and christened 9 Jan 1825 in Helmsley (daughter of James Allenby and wife Christiana Dawson). I find both in the 1841 and 1851 censuses. They married in the 1st Quarter of 1852 (registered in Helmsley). In 1854 they had a daughter, Cordelia Kirby, who died in late June or early July 1857. After this, this couple vanishes. Both (unfortunately) have names shared by siblings and cousins, so it is difficult to untangle the strands of the family. I am wondering if they emigrated -- there are no death records for them and no one in the 1861 and 1871 censuses with similar names matches their profiles. Anyone have any information?
