Have extensive data on John MacDiarmid / Catherine Cameron [McDermid etc. about 1799 of Perthshire, Scotland]. Family resided near Martintown, Glengarry and Cornwall, Stormont County of Eastern Ontario. Branches of this family now reside in most Provinces of Canada, also Wisconsin, Washington, N. Carolina, Tennessee and other States of the USA. Wish to correspond and share data with all that may have a connection with this MacDiarmid ancestor.
