Elva,found a few bits that may help.Looked at Irish records and found the following: birth of John Tisdale/Tisdell; 1822 co Limerick 1827 co Cavan
birth of Elizabeth McKibbon; 1836 co Down
These are on the rootsireland.ie site.
For Frederick Tisdale/Tisdell assuming he was a family member to John Tisdale I found 2 births that may be him: Frederick Cope Tisdale born 4 December 1879 Charlottesville,Norfolk,Ontario parents:Walker Tisdale/Abigail Wood
Frederick Walker Tisdale born:12 March 1874 Vaughan,York,Ontario parents:Joseph Cleoden Tisdale/Maria Nelson Walker
Also a Joseph C Tisdale died on 4 December 1885 in Brant county,Ontario=maybe frederick's father???
There is quite a bit of information on the familysearch.org site on Canadian Tisdales.Worth a look.Hope this helps,Kim
