Surname of the family originally known as MacAonghusa. It is written that they descendeded from Saran, chief of the Dal Araidhe. They would be a part of the Ui Eathach Cobha in what is now County Down and ultimately ruled as the lords/chiefs (both prominently and intermittently) of Iveagh in Rathfairland until the mid to late 17th century. They also held Castle Dundrum from the late fourteenth century until 1601, and for a brief stint from 1642 to the late 1640's.

Some famous McGuinness people include John Martin McGuinness (Irish Republican politician), Deborah Louise McGuinness (co-director and senior research scientist at the Knowledge Systems Laboratory at Stanford University), Ed McGuinness (comic book artist), and John McGuinness (professional motorcycle racer).

MCGUINNESS

A term derived originating from McGeiver, which was then associated to a one McGruber during the superbowl 2009 Pepsi Cola Commercials in which "McGruber" instead of pulling a McGeiver fails to do so and instead drinks a pepsi Cola. The term was then modified to better suit a more talented individual.

Bishop McGuinness Catholic High School

A torturous facility, much like hell, where children must learn a vast array of subject matter which will most likely be of no importance in their future careers. Furthermore, it is a place where fun is not allowed and you will be strongly condemned for any carnival-like activities and actions. Also, you are trained to be robots with no souls or social lives, much like gingers.

Also known as "Bishop McGuinness State Penitentiary."

Bishop Mcguinness Catholic High School

Private catholic school in the heart of Oklahoma City. This shithole is hardly able to be considered "private," because its lacking academics. You'd probably be better off just fucking it and going to John Marshall or Northwest Classen. This school is filled to the brim with plaid skirt wearing whores, who leap at any opportunity to get wasted or stoned. The "men" at this "school" all have small dicks, which they use to rape and assault their female classmates. Its a great enviornment for those seeking a poor education and bathrooms which smell like mango juul pods. The so called Catholics at this school are the furthest from God that one could be.

The Bishop Mcguinness Catholic High School quarterback angrily threw his helmet onto the ground and yelled, punching the air as his team suffered a brutal loss.
