You can look at my 2nd York document transcripts at http://www.ogs.on.ca/services/1812-militia.php where you will also find my email address. Search for the name Chisholm. Please email me directly if you would like to know more about the Chisholm family and their service in the War of 1812. I still have a few questions that I am looking for answers to.
