there are two Thummas in the 1858 Atlas and two in the 1872 Atlas. Two in 1858 are a P. Thumma and an S. Thumma. only ones listed in the index. Both would be in lower Frankford on a current map. in 1872 at different locations, are an S. Thumma, from the business listings a Sa'l., probably a Samuel, a farmer and stock grower. Further west north above Bloserville, in present Upper Frankford is a C. Thumma. This atlas is not indexed.... -- joe
