Mash History, Family Crest & Coats of Arms
Mash is a name that was carried to England in the great wave of migration from Normandy following the Norman Conquest of 1066. The Mash family lived on the border between two territories, such as the Marches between England and Wales or on the English Scottish borders. The name may also have emerged as a nickname for someone born in the month of March.
Alternatively, the name could have been derived from the Old English word "mersc" and denoted a "dweller near a marsh."  
Early Origins of the Mash family
The surname Mash was first found in Somerset where Godard de la Merse was listed in the Pipe Rolls of 1194. Later, Henry del Merse was found in the Curia Regis Rolls of 1212 and William atte Mersche was listed in the Subsidy Rolls for Sussex in 1296. The variant Mash dates back to 1524 when Robert Masshe was listed in the Subsidy Rolls for Suffolk. 
The name is "distributed over the greater part of England, but rare or absent north of Nottinghamshire and Lancashire. It has several centres, namely, in Cambridgeshire and Kent in the east, in Lancashire in the north, in Shropshire in the west, and in Wilts, Dorset, and Somerset in the south. Marsh is the name of a parish both in Shropshire and Kent." 
There are "parishes in counties Buckingham and Lincoln. The Kentish family appear to have been in that county from the XIV. cent. The Latinization is De Marisco, and the medieval form is Ate-Mershe. The equivalent name Marais is common in France." 
The Hundredorum Rolls of 1273 listed Isabel ate Mershe, Oxfordshire and John in le Merse, Oxfordshire.

In England at this time, the uncertainty of the political and religious environment of the time caused many families to board ships for distant British colonies in the hopes of finding land and opportunity, and escaping persecution. The voyages were expensive, crowded, and difficult, though, and many arrived in North America sick, starved, and destitute. Those who did make it, however, were greeted with greater opportunities and freedoms that they could have experienced at home. Many of those families went on to make important contributions to the young nations in which they settled. Early immigration records have shown some of the first Mashs to arrive on North American shores:
