Maude, Mawde, Mawhood, Maut, Maute, Mowit(t), and quite a few other derivations of the same name have been around for many years. Not all of the people with those names are related but a great majority of them are. The name originally comes from de Monte Alto, which was the original name. It was brought over to England around 1066-1070 by Eustace de Monte Alto, who was Baron and Senechal of the County of Chester under Hugh Lupus, the Earl of Chester. Eustace was Lupus's 2nd in command. Eustace had 5 sons and the later barons were descended from Ralph de Monte Alto, Eustace's 3rd son. Around the year 1080-1085, the name was changed to Montalt (or de Montalt) and it remained that right up until the early to mid 1400's when it seemed to morph into Maude and it's derivatives...although Mowit/Mouat seems to be a little earlier than this as it's a Scottish derivative that seems to have been hanging around since 1250-1300. The Maude family were, and are still, quite a prominent family in Yorkshire and a couple of other counties in England, but are mainly concentrated in Yorkshire. The present Viscounts Hawarden are from the family. Since you have family from Bradford, which I do myself (but not Maudes) that are Maudes, there is a possibility that you are related to the main family through a side branch, as they did have possessions and such in the area, plus they had fairly large families.
In any case, I hope that's been of help to you. If you're wondering why I have all that information about the Maudes, I'm a descendant of the main family, myself, and I've done quite a bit of research on the history of the family.
