Hi Andrea,
It's the "other" Dickinson family that you're tied into, although if we go back far enough, there's a good chance there'll be a connection somewhere. I do have an unconfirmed marriage between Eleanor (Ellen) Sankey Dickinson and Joseph Sharp. Ellen was born in 1859.
The Miss Crisp you mention is probably John Harris Crisp's daughter. Her cousin, Mary Ann (Minnie) Johnson taught at the local school in Seaton Sluice for many years. Another cousin, Jen Crisp also taught, although she moved away from the area when she married William Batton. My grandfather, John (Jack) Dickinson, who was a second cousin to Miss Crisp and first cousin to Minnie and Jen also trained as a teacher, although he never worked as one. (I often wonder if his cousins, all of whom were older than him, had taken all the available jobs by the time he qualified!!) He actually moved to Hebburn to find work as timekeeper at Hawthorn Leslie's shipyard.
It fascinates me, that at a time when women were expected to leave school, marry and raise a family, that that particular generation of my family clearly believed in educating their daughters as well as their sons.
The Elders appear first in my family in my great great great grandfather's generation and then again in the next generation. They were seafarers and had moved to Seaton Sluice from Suffolk. When I first started researching my family history, some 25 years ago, I had some long talks with Nancy Elder, who, as a child, had lived next door to my family on Rocky Island.
