Creet Family History

Perhaps a variant of Crate, of which Craft is another, both of them dialect forms of Croft. With the 1562 bearer below, compare Willm Craft 1652 and William Croft 1731 in IGI (Spalding Lincs).

Alternatively, a variant of Creed with devoicing of the final consonant. Compare Antony Creed 1687 in IGI (Stepney Middx) and John Creed 1859 in IGI (Aldershot Hants) with the 1852 example below.

Of French though unexplained origin.
