I feel like I've hit the "brick wall" looking for information on my spouse's great grandfather, Eugene Herley (Herlihey). I am hoping you can help. I've scrolled through 100's of marriage and birth files including ancestry.com and Ontariogenealogy and not finding the marriage (abt 1861-62) of Eugene Herlihey to Mary McNamara. Nor, do I find the birth of their first two children James P (abt 1863) and George Francis (abt 1865). I've seen marriages and baptisms for other members of his family, but not Eugene. I'm open to suggestions on where to look next.Lynden - Ontario did not begin Vital Registrations (of births, marriages and deaths) until 1869. That is why you have not found the ca 1861 marriage and the two births ca 1863 and 1865.
You will have to search alternate sources, which includes church records. I see that you found the family in two early Ontario census records (1851 and 1861). Go back and see what religion they were.
Then check the location where they lived and find out what churches existed for that area in the time period you need. I would then look at Ontario Archives website to determine what, if any, have been microfilmed. You will have to obtain the relevant microfilm(s) and start looking. With any luck you'll find your family!
