Hi Donna,
Many thanks for the prompt reply!
I found the birthdate of Thomas Cleator from the 1851 Census in Liverpool.
It states:-
Thomas Cleator abt 1816 Isle of Man
(Thomas's occupation is listed as a Grocer/Provisions Dealer)
I know they used to "round up/down" birthdates when recording census records, so 1816 may not be exact.
Perhaps he could have been the son of Mary Corlett/Thomas Cleator?
I'm afraid that I don't have much info to go on!
Kind regards.....Sue
