Greetings from Canada, Cousin ~ Definately still a working e-mail address after about 12y ~ otherwise I would miss exciting messages such as your's!
If your Gran was John Ingram CLARK's daughter, she would have been a 1C to my gran, Martha Clark BROWN, which makes you my 3C. My gran was the daughter of Martha Jamieson CLARK & Andrew BROWN.
Wonderful & thrilling as you are the first contact we've had from one of John's descendants. You will have to tell us all about him, etc. Might be a good idea to put John's details on the boards, if you haven't done so already.
There are several of us, from 5 of Martha Clark JAMIESON's & Andrew BROWN's children. Not all of us are actually 2C, as Andy in Scotland & I (Canada) are 1C, as are Carole in Gloucs & Sue in Yks. Paul in Lancs; William & daughter Marnie in Scotland, as is Ali way up in Wester Ross. Jan in Scotland & Yvette in Spain are sisters; Joe & Elizabeth in NSW Australia are siblings. Heather & her 5 sisters are in Qld, Au. Mainly we are 2C & I suppose more than "several" eh? Then there is Jeanette & her 1C in NZ who are great-granddaughters of Thomasina JAMIESON's sister, making them our 4C.
I can be contacted at: amheater[at]cogeco.ca Some of us are also on Face Book (me under ~ Trena Wyatt Heater)
Looking forward to hearing from you and where you are located ~ UK? or elsewhere?
