Hi Bev,just notice this posting tonite.
My grandfathers name was Lawrence William Cotnam and he had three chrildren, Pearl Cotnam,Woodrow Lawrence Cotnam (my father) and Basil Clifford Cotnam. My grandfather moved from Vermont to Pembroke,ON,CANADA when my father was very young, approximatley 70 years ago.
My father recently passed away and I know very little, but with the help of my sisters and Mother, can piece a great deal together.
I would be interested in hearing more, if this clan sounds familiar. Also, my grandfather married Ada Burgess of Beachburg as well, the Island you speak of is a big part of my families heritage with many of my relatives living there at one time or another.
