1. Medieval Mowbrays had their name spelled in the 1200s as Moubray,
Mombray, Mumbray, Munbray, Muntbray: but by the 1300s almost exclusively
it was 'Moubray' :  Mowbray came in during the late 1300s and 1400s, and
the version 'Moubray' only survived in Scotland. We still have in
England a family of Mumbray.
2. There are about 18 separate (at least they are separate until any
researcher manages to identify the links between them ) large  or
widely-spread Mowbray families (some of whom spell their surname quite
differently). These are -
(a) from Scotland: families from Edinburgh, the villages to the
immediate south and west of Edinburgh (for example
Cramond and Dalmeny), and from Dunfermline (just across the river Forth
from Edinburgh). In this area since the
Early 1200s.
(b)  from Ireland:   families from County Londonderry/Derry who resided
at Cumber, Curryfree and Coleraine; and from
      County Donegal, where they came from Cramond near Edinburgh about
1720. The Cumber and Curryfree
      Families spelled their name Mooberry and Moubray throughout the
1700s, and one branch ended up as Mulberry.
      Mooberry is also found (more rarely though) in Scotland in the
1700s, and almost never in England. A huge proportion
     of the population of County Londonderry came from Scotland
throughout the 1600s and early 1700s, although
     there is a possibility that these 'Mowbrays' had  (again Scottish
and from Cramond) roots there from the early
     1600s.
(b) from England:  County Durham.two main families of Mowbray, one from
Bishopley, in Weardale, and the other from Bishop Middleham and
Plawsworth.    Yorkshire, two main families, one at Almondbury near
Huddersfield from about 1700, and the other from Finningley near
Doncaster from about 1650 (this family had a large 'offshoot' at
Ashover, Derbyshire, from about 1750 onwards).  Lincolnshire, two main
families, one at Fishtoft (David's line)
and the other at Bardney from at least the 1400s onwards.
Leicestershire, again two families, one from Burley, Rutland in the
1500s, which went to Leicester; and the other at Shepshed from about
1750. Also probably from the Burley family were the now widespread
Mowberry family.   Herefordshire, at and around Bromyard, a family
stemming
from a probable Scottish Mowbray immigrant around 1670.  London, where
the oldest traceable families who still exist stem from Mowbrays in
Clerkenwell in the 1790s and a family now using the variant spelling of
Mowbrey who
are descended from a weaver in Shoreditch again in the 1790s.

There were also a few other families of Mowbray living in the same
counties, whose exact links to any of these above-named families are
unknown at present.     For example the Mubery family from Dumfries,
Scotland, who moved down
To Liverpool and abroad, and some of whom have changed 'back' to
spelling their surname 'Mowbray'.
