I'm nearly that far... I've got a Thomas Hewitt who married Phoebe Mercer in 1786 in Liverpool. I have several possible baptisms for him but nothing conclusive.
I have now put quite a bit of family info (pre 1700) at my blog howetfamily.wordpress.com. My Howitts came from Howets from Hewitts from Hewets and Huets probably from Huwets. Cheers.
