I would like to obtain a copy of the will of Satterlee Clark who died Mar 1, 1848 in Washington D.C. I have the following information: will dated 2-14-1848, probated 3-27-1849: Book 6, pp.230-231; O.S. 2924; Box20. Can anyone tell me where I should write to get copies of the will and probate proceedings? Thanks for your help. Sharon Stanfield
