Mullen gang leader and Bobby’s brother was married to Margaret Greig. Her identical twin sister, Catherine Greig was married to Bobby. The Greig sisters had a younger brother David Grieg. Paul McGonagle was murdered by Whitey Bulger who had also killed their brother Donald McGonagle a couple years earlier. Catherine later divorced Bobby before taking up with Winter Hill Gang leader Whitey Bulger. David Grieg allegedly committed suicide (even though the gun was found far away from the body) in Cape Cod a couple of years later.
Trust me – it’s way more complex than this.
Final Resting Place:
New Calvary Cemetery
800 Harvard Street
Mattapan, Massachusetts, 02125
Grave Location:Section 8, Grave 1396
Grave Location Description
As you enter off of Harvard Street, drive straight on Apostle Avenue and past the office on your right as the road begins to curve to the right. Park at the intersection of Apostle Avenue and Ascension Avenue. The McGonagle family monument is 20 feet from the corner of Section 8/8A, under a tree.
The confusion occurs when you look at the cemetery map Section 8 is bisected by Apostle Avenue. Bobby is buried in the short Section 8 on the left when you drive in from the entrance.
