Fiona, I am so excited to have received your post. We definitely have a match. Helen Campbell Orr who married J. Dunlop was my grandfathers sister. They were the children of Janet Whiteford and Thomas Crawford Orr. Janet Whiteford was the daughter of David Whiteford and Janet Crawford.
David and Janet has 11 children and I have connected with the families of about 4 of them. You now have a very extended family..This is very exciting. My email is angels4me2838@aol.com.....please feel free to email me. I have sent your post to a cousin in Australia . He will be delighted too. I live in New Jersey in USA......Hoping to hear from you....Penni
