In 1898, my maternal grandfather Henry Leon (Joselyn) Harvey was born to Henry Joselyn and, although not listed on the birth certificate, mother Annie Penner Milton. Dr. Leon Harvey gave the boy the Harvey name. Annie began going by Mrs. Joselyn. Henry Joselyn disappeared into thin air. After Dr. Harvey died in NY in 1912, Mary Tinker Harvey lived with Annie Joselyn and sister-in-law Isabel Harvey in Glendale, Ca. Mary Tinker Harvey died in 1921 and is buried in New Rochelle, NY

Any info about any of these people would be appreciated.
Thanks
