Perhaps surprisingly, when Gov. Shepherd’s first-born child and original namesake, Alexander, died as an infant in 1864, Shepherd turned away from Rock Creek Cemetery and purchased a plot in Corcoran’s Oak Hill Cemetery. The reason is not documented, but it could have reflected the ambitious Shepherd’s wish to improve his social status and relationship with the powerful Corcoran. Within four years two more Shepherd infants, Alexina and William Young, were buried in Oak Hill. Shepherd’s parents-in-law, William P. Young and Susan B. Young, who died in the late 1860’s, are also buried there, as are Gov. Shepherd’s second namesake son Alexander and his wife Phoebe Elliott Shepherd. From the split between Shepherd and Corcoran around 1870 until 1943, no Shepherd family members were buried in Oak Hill Cemetery—all are in Rock Creek Cemetery.
