Hi Pat, I am also researching my family tree and I am a cousin of Peter's. My g-g-g-g-g-g grandfater was Thomas Deacon from Wexford. I live near Ottawa, Ontario Canada in the same county where Mary Deacon and her children first settled..about 5 miles away. I'd love to correspond and compare notes with other members in our family.
Our family owes a great deal to Peter for his efforts detailing our family tree. His research gave me a huge headstart in my research. I've basically been chasing him around the internet, poaching his research! ;-)
It seems now we are both stuck at the same point, namely the period of time from where Mary left Ireland back to the first Deacon of our family to arrive in Ireland. From there who knows!
Please contact me, my email is public and I'd love to hear from you.
