Not sure if you ever got the certificate, J, but here is an update:
Wilhelmena Smallwoods
Birth 15/05/1912 in Lower Cumber, Londonderry, Ireland
Death 29/01/1973
As suspected, she was a daughter of the James and Elizabeth of the census link in previous post.
James Smallwoods and Elizabeth Smallwoods (yes, to her maiden name) married in 1892 in Blantyre. They were not there at 1891 and by 1894 were back in Ireland.
James was son of Samuel Smallwoods and Elizabeth Dallas.
Elizabeth was daughter of Joseph Smallwoods and Eliza(beth) Simpson.
