Thomas Mansfield, born Delaware, 1779(?) moved in to Washington DC by 1816, where be married Ellen/Elenor Parris. Next generations, all, Washington DC: Thomas, married Sarah E. King. Next gen, Thomas, married Anna E. Wood. Next gen, Thomas, married, still in DC as of 1930. Would really appreciate some help, esp with the Delaware roots, where I dead-end. Thank so much.
