Happy New Year Chris, I have only been able to trace one senior Orchin in N.I. Henry and Sarah had a son Fred born here in 1854, He in turn had a son Fred born here in 1900. Church records and Public Records confirm. H + S had, a least, 9 children but official birth records only date from 1864. I must assume they may be in some Church Records. Which church/churches is the problem. I do, however, have copies of all their marriage certificates but the 2 wives you mention do not tally!
1864: Elizabeth m Wm John Nesbitt
1866: Thomas m Mary Neilly
1869: George m Jane Montgomery
1872: Wm John m Hannah Pepper
1876: Sarah Jane m Wm James Brown
1876: Henry m Bridget Eustace
1878: Frederick m Sarah Jane McMeekin
1883: Joseph m Margaret McMeekin
1883: Charles m Elizabeth Prentice
I am curious about Ellen b.1856 near London. Could my Henry be her uncle? What other info do you have on Ellen? Also do think you are related to any of these Orchin's? My direct line of research is through Frederick. @be for now, Davina.
