Ottawa Valley Irish is a website maintained by M.C. Moran. It's one-half database, containing his Irish and French immigrant family tree, and one,half guide to doing Irish genealogy in Ottawa and wider Canada. The introduction outlines that:
This website covers the family histories of a number of Irish and French Canadian families in the Ottawa Valley area, including the Morans of Huntley township; the Laheys and Killeens of March township; the McGlades of Perth; the McCarthys of Kitley township; and the Derouins of Otter Lake.
It also offers tips and tricks for the pursuit of Irish and Canadian genealogy: how to trace your Irish ancestry through Canadian sources; how to search the census records and census substitutes; how to decipher, translate, and interpret the Catholic parish records; and more.
The second paragraph of the introduction is achieved through Moran's blog posts. Interesting examples are highlighted from various records, such as this example of a marriage blessing. Many Catholic records in Canada were written in French, so it is very useful to see Moran's translation of these documents.
