Samuel KING (Sam junior) was born 23 May 1892 in High Halstow, Kent, ENGLAND son of Samuel KING and Mary Ann KING (NEE SCRIVENER). Mary Ann was called Polly by her husband.
Samuel KING (Sam senior) was married (to Mary Ann SCRIVENER) using the surname GRASBY but his birth was registered under the surname HAMPSON (because his father had changed his name from Thomas GRASSBY to Henry HAMPSON).
Family rumour has it that someone deserted the army and Sam junior seems a likely candidate, so he may well have felt that he needed to change his surname to cover up his tracks..
He may have used his mother's maiden name, SCRIVENER, or his grandmother's maiden name, KEMPSTER, or reverted to his birth name, HAMPSON, or reverted to his father's birth name, GRASSBY.
I would like to sort this mystery out as my grandmother (Sam's sister) didn't really know what happened to her brother and now never will and that thought makes me sad. He deserves to be found and his details added to those of his other 10 siblings.
