I am tracing my Baird line. I have got to John B. Baird b.1666, Aberdeen, Scotland d. Apr 1755 Topenemus, Monmouth City, NJ. Son was Andrew Baird 1700-1773. Wife was Mary Bedent according to family sources. Looks very similar to your John Baird and Mary Bernard Osborn. Would like to discuss this with you. John B's father was John m. Janet Banantyne to my source. No further details.
