Please forgive me if I'm insulting your intelligence Margaret, but are you 100% certain and happy with Agnes' parents being Francis Boyd and Catherine Hyman.  I only ask because I've found the birth of an Agnes in 1830 Rathmore, Antrim with parents Francis Boyd and Agnes McKeig - just wondered if maybe Catherine was a red herring somewhere.  However, if you are perfectly confident your Catherine is correct then obviously this is not the right Agnes I've found.  I will keep digging!
