Robert (Bobby) Paul Sinclair, Sr. born on June 1, 1934, to Betty Dolan Sinclair and Paul Andrew Sinclair, passed away peacefully on November 18th at the age of 90. A native Atlantan, Bobby attended Marist High School and the University of Georgia. On August 20th, 1960, he married Margaret Buxton in Columbus, GA and a year later they had a son Robert and four years later a daughter, Betty. They lived in Atlanta until 1970 when Bobby accepted a job with Rozier Machinery as a Caterpillar heavy equipment salesperson, and the family moved to Florida. Bobby loved raising his family on the water in Florida, where he taught his kids to sail, fish and water ski. He was happiest on the Gulf of Mexico on one of his many boats. He was a self-described "tinkerer" of fixing boats, lawn mowers and many gadgets. He was an avid reader and had an incredible thirst for knowledge. His family and friends were constantly amazed at his unbelievable memory and trivia knowledge. He also enjoyed building things; one time he built bookcases just to hold the encyclopedias that he bought for his children. He had a fabulous sense of humor and always had his friends, children and grandchildren in stitches with his stories of growing up in Brookwood Hills, his time at the University of Georgia, living in Atlanta and his many boat adventures. He was an active member of the Bradenton Kiwanis Club for many years and loved the luncheons, volunteering and connecting with other Bradenton businessmen. In 1989, Margret and Bobby moved to Lake Lanier where they continued their love of living on the water and boating. During their years at Lake Lanier, they would become grandparents to 5 grandchildren. They enjoyed traveling to see their daughter and her family in California, spending time with their grandchildren in Atlanta, taking cruises and visiting family and friends. Bobby is preceded in death by his wife Margaret. He is survived by his son Robert and his wife Cindy, their children Trey and Sarah and her husband Ryan. His daughter Betty and her husband Marcos and their sons Marc, Jackson and Andrew and his wife Madi. He is also survived by his great grandchildren, Caden, Ella and Aubrey and his nephews Chip Sites and Paul Sites.
