Hi Douglas,
Thanks for posting the photo. It is wonderful!
I found this record in my database... don't know if you have it.
" Thomas Russell married Annie Lyness in Seagoe parish on 3 March 1902. Annie was the daughter of John Lyness, a labourer from Drumgor."
I am surmising she belongs in this family, but she could be a neice of Jane Lyness, not a sister.... based on the year of the marriage.
