Welcome to the Forum, Val57. (You probably now hold the record for responding to one of the longest outstanding questions!)
Unfortunately genie seems to be no longer a member here and so in all probabliity won't see your response. However, other Forum members might well be interested to hear about anything you know concerning this gentleman. The Sheldon surname is quite significant in Warwickshire and Staffordshire history and it's interesting to see someone bearing it also having been given a non-Gentile forename.
