The Ollis Coat of Arms illustrated above was drawn by an heraldic artist from information officially recorded in ancient heraldic archives. Documentation for the Ollis Coat of Arms design can be found in Burke's General Armory. Heraldic artists of old developed their own unique language to describe an individual Coat of Arms. In their language, the Arm (shield) is as follows:

"Gu. on a fess embattled ar., two fleurs-de-lis sa."
When translated the Arms description is:
"Red; on a silver embattled horizontal band, two black fleurs-de-lis."

Family mottos are believed to have originated as battle cries in medieval times. A Motto was not recorded with the Ollis Coat of Arms.

Individual surnames originated for the purpose of more specific identification. The four primary sources for second names were: occupation, location, father's name and personal characteristics. The surname Ollis appears to be patronymical in origin, and is believed to be associated with the English, meaning, "descendant of Olley." Different spellings of the same original surname are a common occurrence. Dictionaries of surnames indicate probable spelling variations. The most prominent variations of Ollis are Olleys, Olley, and Olli.
