Hello Patricia
Hertfordshire this is it obviously no ?
May be this is too late, but Neboth is also a family name.
It could be written as Nebout, Nebbout and related to jewsih genealogy.
Nom de Tribu: Nabitz origine berbère qui viendrait du nom de différentes tribus du département de Constantine en Algérie Autres orthographes :Nabet ,Nabets, Nabit , Nebout , Neboth
They came originally from south of France, and they are quite numerous .....

Quite no simple, I 'm myself looking for Gibraltar in the year 1800 and I 'am totally lost...
Good luck.
Laura from France
