Pam, John Charles SNELLING b.1/11/1859 was my great grandfather; g/grandmother, Caroline Emma Filce. Their daughter Gertrude Lillian Snelling was my grandmother. We were close. JC's parents were William Snelling and Esther Whittington (there can be no doubt about the latter as my grandmother knew her and told me about her and family traditions about their relationship to the legendary Dick Whittington, thrice Lord Mayor of London). William's parents are Thomas b.4/2/1780, (in Crawley Sussex) (not sure how strong this date/place are; I haven't done much family research in recent years) and Ann Tullett.
There are a number of Snellings & descendants I have corresponded with in UK including Susan Fowler who may have already anwered your queries?
How, may I ask, are you connected? Don Barry, Brisbane, Qld, Australia.
