Family of James H. Towson and Sophia A. Janney

You can find several Towsons buried in the Oak Hill Cemetery in Washington, D.C. The most famous resident would be General Nathan Towson, who, along with his wife, Sophia Bingham Towson and their three children, Caroline Towson Caldwell, Sophia B. Towson, and Edward Southard Towson, is buried on the cemetery's North Hill in Lot 67. But there are 12 additional Towsons known to be buried in Oak Hill Cemetery, with no apparent connection

Joseph Towson and Sarah Yundt

I believe this couple may be the Joseph Towson who married Sarah Yundt, daughter of Leonard Yundt,  on April 28th, 1814 in the First Methodist Church by Rev. W. Ryland (Methodist Records of Baltimore City, Maryland, Volume 1: 1799-1829 by Henry Peden, Jr.). Joseph Towson may be the eldest son of Shadrack and Rebecca Towson, to whom Rebecca transferred administration rights to Shadrack's estate in 1813 [source].From at least October
