Yes, I have a Franciszek Tomoń but maybe not the same one you are seeking. Do you know what year he was born? Mine was born about 1856.
My grandfather, Michał Tomoń, was born 1887 at Golcowa, and arrived in the USA in 1903. His parents were Franciszek Tomoń and Apolonia Bogaczewicz, and grandparents were Sebastian Tomoń, and Apolonia Kudło. I don't know of any Tomasz in these families but it is possible.
