That looks like an 'N' to me, written like a large 'n' shape for upper case - I find that sort of thing a lot in the written records I'm using for my PhD (try reading Victorian doctors' handwriting - uurgh!). Also, loads of my family have been confusing me by interchangeably using first/middle names on different censuses - a Richard morphed into a William, but they estimated different birth years on different censuses, but then it transpired everyone knew him as Bob. His son was called Alfred John, and he flits between those and Jack - maybe that's what's going on here? Does anything come up for 'Ellen Luce(or Lucy)' or vice versa, perhaps trying it with both surnames?
