My mother spent a great deal of time researching family history and I have inherited all her records.It would be interesting to see if we have any common links!
Her information says the name derives from the medieval practice of creating a surname from a nickname or a personal name, in this instance, one that would be used of someone who resembled a bird in some way, derived from the old Englosh (poss 7th century) Fugol, meaning fowl or bird.It was first recorded as a personal name in the Domesday Book of 1066 'Fugol' of Winton Hampshire.
I have a very poor photocopy of the Fuggle family crest with the motto 'En Foy Prest' which translates as 'In Faith Ready'.Quite similar to your version.
I can find references to quite a few Fuggles in Tenterden - I have a Richard (baptised 5/4/1646) who married Mary Hoford on 22/12/1675.They had3 children, Elizabeth, Richard and Thomas.Richard married Ann Lacy at Tenterden on 2/4/1700 - they had 7 children, Richard, John, Elizabeth, Thomas, Mary, William and Sarah.
If any of these are who you are looking for, please contact me and I'll send you what I've got.
