I wonder if it was Fleet,spelling was a bit haphazard in those days.
There was a river Fleet in London of course and perhaps one near the place
you are interested in.
But it talks about heraldry,arms —-Argent, a Wolfe passant sable.
Silver -a black wolf walking to the right with paw raised to the right.
Try looking for those terms as they could be that family’s arms.
Viktoria.
