Trolley History, Family Crest & Coats of Arms
The Scottish Trolley surname is most likely a habitational name, taken on from a place name; perhaps from the Gaelic "Traill Creek" which runs into Upper Loch Torridon.
Alternatively, the name could have originated in Normandy, France. In this case they claim descent from " the castle of Trely, in La Manche. "Two barons of this name appear in England, sub-tenants of the great Honour of Verdun."—Sir Francis Palgrave. The Trelys or Traillys are said to have been a branch of the noble family of St. Denis-le-Gast, of whose barony their Norman fief formed part. Lysons mentions them among "the earliest extinct families" that held property in Bedfordshire." 
Early Origins of the Trolley family
The surname Trolley was first found in Bedfordshire (Old English: Bedanfordscir), located in Southeast-central England, formerly part of the Anglo-Saxon kingdom of Mercia, where they were Lords of the Manor of Yielden and other estates in that shire as shown in the Domesday Book taken in the year 1086. 
Geoffrey de Traillgi, a knight at the Battle of Hastings, was an under-tenant of the Bishop of Coutances. He was originally from Trelly in the arrondisement of Manche, Coutances in Normandy. Geoffrey also held Teign, in Devon. 
The family joined the many Norman nobles who moved north into Scotland.
Some of the first records of the family in Scotland include: Thomas Trayle, Canon of Aberdeen in 1366; and Walter Trail (Trayl, or Treyl, or Treyle), of the family of Traill of Blebo in Fife, Bishop of St. Andrews in 1385.

The motto was originally a war cry or slogan. Mottoes first began to be shown with arms in the 14th and 15th centuries, but were not in general use until the 17th century. Thus the oldest coats of arms generally do not include a motto. Mottoes seldom form part of the grant of arms: Under most heraldic authorities, a motto is an optional component of the coat of arms, and can be added to or changed at will; many families have chosen not to display a motto.
Motto: Discrimine salus
Motto Translation: Safety in danger.
