Sue: Thank you for the confirmation re Mary Ann's illegitimate birth.
The KENYON and MONK particulars you mention, I do have, but I appreciate the trouble you have taken.
The burial entry for Martin Kenyon 2 Feb 1872, was the father of Martin Kenyon 1811-1840 (Will transcription referred to previously).
I do not, however, have any record of a Bertram Kenyon and when I checked the IGI found no record. Another possible member of my tree perhaps.
