I'm also looking for info on a John Baird (b abt 1836) however he's from Scotland. He was married to a Catherine Currie 06 Sep 1864, in Beith, Ayr, Scotland (batch M115811, dates 1855-1875 call no 6035516, register of births, deaths & marriages of Scotland.) His parents were James Baird & Grace Burgess, children were Jane Bain Baird (1865), Peter Currie Baird (1866), Grace B Baird (1868) & Catherine Currie Baird (1872), but that's about where my info stops. I also have info that there's an Agnes Baird to "unknown mother".
So - sorry about sort of hijacking your thread, but if anyone's looking for John Baird (1836) from Scotland, please let me know.
