Donald Beaudoin's very extensive genealogy includes the Massicotte family of Quebec, some of whom changed their name to Masker and Mesker upon migrating to the United States. Don sent me a portion of his genealogy, as a PDF document, in September, 2015. In many cases, Don compiled his material from the family history of other people who did the original source document research. Those other researchers are not named in the PDF document, and so I have not been able to acknowledge them here.
