Re: Lockport, NY Jellings (& OH) via England
I'm pretty sure that the Ben in your list of Jellings is Benjiman (Benjamin) Jellings who married Winona Sylvester, daughter of Jerome Sylvester. In the 1870 and 1880 censuses, Winona was called Miama, an interesting name. Ben and Winona had one child, Hellen (Helen) M. Jellings. Ben, Winona, and Hellen were living with Jerome Sylvester in the 1910 Census, Lackport, NY.
Hope this little clue helps.
