I can find no record of a Sarah Jane Henderson born in November 1883 in Northern Ireland, nor can I find a marriage there for parents George S. Henderson & Jane Stewart. What’s the source of your information?
There are a number of trees on Ancestry (eg Chaba family tree) that have a family looking a bit like this. Father is George Somers Henderson but the mother is Margret Redford. This family lived near Morpeth, Northumberland (England), though the trees show Sarah J Henderson born in Horton, Northern Ireland. I can find nowhere called Horton in Northern Ireland. There is however a Horton, near Morpeth, in Northumberland. I’m wondering if perhaps someone has confused Northumberland with Northern Ireland? Perhaps on a hard to read census or similar document?
The indexes to the English marriage records do list a marriage, registered in Morpeth in Oct – Dec 1865, between a George Henderson and a lady with the surname Redford. George Henderson was a coal miner and was born in Horton, Northumberland c 1840. He did have a daughter Sarah J, aged 9 in the 1891 census (21 Cowpen Square, Horton). The census also shows her born there.
Many of the Ancestry trees show Sarah in Northumberland in the 1891 census, before moving to Winnipeg where she married Edward Burgess in 1902. Is this the same family? If so, I think there may be some confusion about Sarah J’s birthplace and mother. Do you have her marriage certificate, and if so what parents names appear on it?
