Arthur Conrad Sinclair Jr., 80, passed away peacefully on March 23, 2025, at 4 p.m. at Monadnock Community Hospital in Peterborough, after a long and courageous journey. At his side, holding his hand, was his beloved wife, Betti Sinclair, along with her son Keith Arnold and his wife Stephanie.
Born on July 12, 1944, Arthur was the second child and first son of Arthur Conrad Sinclair Sr. and Alice Mary Louise Sinclair. He grew up in Laconia, and graduated from Laconia High School in 1962. Shortly after, he proudly served his country in the U.S. Army, stationed overseas in Germany.
Arthur leaves behind his devoted wife, Betti; her son, Keith Arnold; his two children from his first marriage, Wendy Sinclair and Christopher Sinclair with wife Melvie; his siblings, Nancy Spear, Mary Day, Melissa Gomez, Jayson Sinclair and Shawn Sinclair; seven grandchildren, three great-grandchildren; many nieces and nephews.
Arthur was a man of warmth, humor and kindness, and he left a lasting impact on all who knew him. His family finds comfort in knowing that he is now reunited with his parents and his sister, watching over all of us from Heaven and undoubtedly having a wonderful time. Rest in peace, Arthur, until we are all together again.
