My family has several Cost connections in Maryland that I can trace to the mid-1800s.My gr. gr. gr. grandfather's sister, Rebecca Parks, married George Cost around 1850 and they had a son named George N. Cost.In addition, my gr. gr. gr. grandmother's sister, Sarah Shackelford, married a John Cost around 1842 and they had two children Lewis Cost (whom I believe fought in the Civil War) and Mary Cost.Family lore also suggests that the son of my gr.gr.gr. grandparents mentioned above, William H. H. Parks, married a Cost, Ann Cecelia Cost.The connection remained strong and my gr. grandmother was named Rebecca Cost Parks.Does anyone know of these Costs?
