Maggie, yes most of my info has come from the two censuses...I believe we can say with some certainty that David Montgomery and Rose Smith were indeed the parents of William, who married Jane Boyd...I have both marrriage records...the date is perfect, both married in Broughshane 1st Pres. and William's children bear both parents and g/parents names, including 3 having the middle name Smyth. David's father was also called David and a labourer...estimate b. c.1818. I have checked the Woodburn Pres. records so have got a number of birth dates for Ellen's siblings. It would be great to share our info and try to bring the tree up to date. By the way I'm from Ballygally...and you? Lookin to hear from you. Have you come across a townland map for the Braid area?
