In the NY Biog. & Genea. Society's "Minisink Valley Reformed Dutch Church Records, 1716-1830" which retains original record spellings there are these additional variations of Titsworth: Ditsoort, Ditzoort, Tichort, Tietsoort, Titcherd, Titchsord and Tithoor but no listing for Elias. This book covers the churches of Minisink, Mackackemeck and Walpeck in the tri-state area of northwest Sussex, Pike Co, PA and Port Jervis, Orange CO., NY. Perhaps the spellings starting with "D" will give you new avenues to explore? Good Luck, Cathy DiPietro listowner NJSussex-L
