I am also looking for a John Baird. Mine is John F Baird. Family 'history' says he was born in Scotland. He was in Missouri when my great grandfather was born in 1866. His name was William Preston. He had a brother named James Alfred Baird (who never married) and a sister Dilah who married a Copeland and lived in Texas. James F Baird went to Texas twice to homestead. I think it was in Parker County. I believe the next three children were born there. James F Baird married again and had Henry Baird, Sam Baird, and Mary Baird - all who remained in Texas.
I would appreciate hearing from you about your John Baird.
