He has three half sisters...His mother’s marriage fell apart “days” after it took place in 1942 and he was born 9 months later in 1943, adopted by his stepfather Gingrich... I never knew he was not raised by his own father and didn’t realize it was his stepfather who had been the military officer.
Wikipedia:
“”Gingrich was born at the Harrisburg Hospital in Harrisburg, Pennsylvania on June 17, 1943 as Newton Leroy McPherson. His mother, Kathleen “Kit” (née Daugherty; 1925–2003), and father, Newton Searles McPherson, married in September 1942, when she was 16 and McPherson was 19. The marriage fell apart within days.[7][8][9] In 1946, his mother married Army officer Robert Gingrich (1925–1996), who adopted Newt.[10] Gingrich has three younger half-sisters, Candace Gingrich, Susan Gingrich, and Roberta Brown.[10]””
“”didn’t realize it was his stepfather who had been the military officer.””
Sorry - that would be his father not stepfather, because he was adopted!
