The Times spotlights the activities of some of Rep. John Murtha’s family in this article.

The congressman earmarked millions of federal dollars to an institution in his district, St. Vincent College, while the Rev. John F. Murtha, his cousin, was its president. He has directed millions more in earmarks to clients of a firm, KSA Consulting, where until about three years ago his younger brother, Robert Murtha, known as Kit, worked as a lobbyist.

Colonel Murtha is one of Kit Murtha’s sons. Another son, also named Robert Murtha, is a former Marine with a master’s degree in engineering. He previously worked for two military contractors who, seeking earmarks, hired a lobbyist with close ties to Representative Murtha.

Over the last three years, the younger Robert Murtha has operated Murtech Inc., a small contractor in Glen Burnie, Md., that runs a warehouse and offers engineering services. It has received more than $3.5 million in military contracts over the last three years, not including subcontracts through other companies.

He is also a founder of another company, Ocean Energy Systems Inc., which is seeking federal financing to support its research into the generation of power from the motion of waves.
