I am very familiar with the Perkins/Parkins and Whitmans you are looking for. Mary Watts Perkins was born about 1830. She was the oldest child of Thomas Watts Perkins and Mary Coulter. Mary was married first to George Whitman. The children I have for George and Mary were: Elizabeth born 1848, Sophia born 1850, Margaret born 1852, Robert born 1854, William born 1856, Mary C. born 1858, George born 1860 (died as infant). Mary's second husband was Holly Childers. She married him in 1865. Born to Mary and Holly Childers were: Susan Melvina 1866 and Julia 1868. I am a Coulter researcher and there are many, many links here.Email me and will give you loads of info.
