Bobbie Sue Mack, affectionately known by her family as “Tutti”, was born on July 7,1953 the third of seven children, to Eula Mae Cummings and John Henry Cummings, Jr. The Lord called her home to Glory on May 2,2026. Bobbie attended D.C. Public schools and graduated from Theodore Roosevelt High School. Quite the socialite, there was never a dull moment with her! The Roosevelt Rough Riders knew exactly where to go for a great Friday night party in the Cummings basement. This continued into her adult life where she’d have fantastic barbecues in her back yard where everyone was invited. She worked for Washington Gas Light Company (WGL) in various management positions from 1971until retiring in 2008. Bobbie furthered her career in 2008 working for D.C. Tax Assessment Office and became a manager until she retired in July 2025. While employed at WGL she met the love of her life and cherished husband, William Henry Mack, Sr (Mack), and married in 1976 on Valentine’s Day. From their marriage, they welcomed William Henry Mack, Jr. She and Mack birthed BHM Contractors a property maintenance company. They enjoyed 45 wonderful years of marriage until God called Mack home. Together, they were involved in causes near and dear to their hearts. Advocating for the youth of Prince George’s County. She served on the Board of Directors of the Kettering/Largo/Mitchellville Boys’ and Girls Club. They founded the KLM Steelers Club where they helped many young athletes to go on to college and professional sports. She took pleasure in attending football games of her son, Billy, both with the Boys’ and Girls’ club, Gonzaga College High School and at the college level. She was a strong advocate for the citizens of the State of Maryland and was a long time Maryland elections’ official, appointed by former-Governor Martin J. O’Malley. She served as a past chair of the State of Maryland Board of Elections, as well as chair of the Prince George’s County Board of Appeals and the County Board of Zoning Review. She actively campaigned for several political figures including former Governor Parris Glendening, former State Senator Ulysses Currie, former U.S. House of Representatives member Al Wynn and State Senator Steny Hoyer. A very important thing to her was that the citizens refer to the county as “Prince George’s County,” vs “PG County.” Her stance on that issue was the epitome of “County Pride”. This mission was expressed in her longtime advocacy in Largo Homeowners’ Association. Family and friends meant so much to Bobbie. She had a special love for her nieces and nephews. It was commonplace for her to call them to stop by for a cookout. This was something she loved to do. Being such a personable, warm, giving person, it was her pleasure to get folks together to fellowship amongst each other and to have a great time. Bobbie was preceded in death by her parents Eula Mae Cummings, John Henry Cummings, Jr and her beloved husband, William Henry Mack, Sr. She leaves to cherish her memory son, William Henry Mack, Jr. grandson Sir William Henry Mack, III, her sisters, Willie Garrett, Brenda Ceasar (John), Denyse Cummings Stuart, Robyn Cummings Coles (Tony), Lisa Langley (Ronald, Sr.) and her brother, John Henry Cummings, III (Jeanine). along with many nieces, nephews, great nieces and nephews, other relatives, colleagues and friends
