Have information re: Alexander Murdock who married Elizabeth Davis in 1770 in Ulster County, NY. Had 6 children. We belong to son James Alexander Murdock,( Feb 25, 1780-Sept 7,1848. Died in Arena, NY) through his son Nathan,( ?-1879 Livingston Manor, NY). Does this fit into anybody's research? This document dates around 1935. Lots of info on descendants who headed out West.
