Oscar Llewelyn Herb (b. Apr 1886 Philadelphia d. ? probably Baltimore City, MD) was married to my relative, Grace Coleman (1891-1967). There are copies of his World War I and World War II registrations at ancestry.com. The couple lived in Baltimore City, MD. Grace's parents were James Coleman (b. 1854 MD) and Annie (maiden name unknown at this time). She had 8 children in 1900 census but only 5 are listed living with them. See 1900 census Baltimore Ward 15, Baltimore CityRoll 614 Page 13A, Enumeration District 194. If you would like more on Grace Coleman's family let me know.
