In the Leeds Intelligencer of 7 Aug 1770 - there is the attached report! I do hope it's legible to you - but if not, it reads (with the letter 's' now substituted for the printed 'f').
'We are advised from Hull, that a few days ago, a person, who adopted the name of William --- , and in that character had served several gentlemen of that place as a domestic servant, giving general satisfaction, was safely delivered of a fine girl, to the great astonishment of all who knew HIM.'
(Presumably it wasn't a huge surprise to EVERYONE!)
