Fitzgerald, from Ireland to Hastings Co., Ontario

A reader is looking for information on William Fitzgerald (born in Ireland about 1816) and his wife Ellen (born in Ireland about 1813). The couple emigrated from Ireland, and came to Hastings Co., Ontario in 1843. One of their sons, John Fitzgerald, married Mary Ann Hickey in 1864. Many of the family are buried at St. Ignatius R.C. Cemetery in Maynooth, McClure Township, Hastings Co., Ontario.

Any information would be greatly appreciated.
