In his will of 1914, my 2g-granduncle, John H. DRURY, refers to his niece Louise NICODEMUS (he later refers to her as Lu Lu Nicodemus, too). In checking for NICODEMUS in D. C., I found the following - I would love to have her parents, so I can try to see how she connects as his niece! Other relatives in the will include the surnames SCHAEFFER, SHEAHAN, GULICK, and CALVERT.
