Hello Ms Leslie,
I hope you still monitor this site occasionally. James Waters was also my great-grandfather. I'm the grandson of his youngest son, Leonard, who also emigrated to the US early in the 20th century. I'm guessing that Harriet and Harry came into the US through Boston and perhaps settled around Lawrence MA. Leonard did, before moving to Southern New Hampshire, which is where I live. You have much more information than I do. In fact, until I happened upon your post my knowledge stopped at our great grandparents. I hadn't been able to find them prior to 1890 in Glossop/Whitfield. Family legend had them at 43 Primrose Lane and thought the 1890 census didn't give an address, it did have them in Whitfield. Leonard died when I was a baby, so I have very limited family knowledge. I'd love to share any family information.
I'll also send you a message directly. Hope to hear from you.
Jim
