I was sent information on the English tickles by a cousin of mine. She wrote an unpublished book (just for a few family members) on the Tickle family and its descendants. The information came from a further cousin who spent some time in England researching the family tree. The marriage date and place for Thomas and Jemima that I was given was September 1867 in Sheffield; the book says that Thomas fathered children with Jemima before that date.
