Hi Doreen,
There is only one reference to a Janet Cleator on freeBMD being a death March 1888 Whitehaven (Cumberland) Vol 10b p411 age 75. I also found a Jane Cleator born Scotland 1811 living in Cumberland in the 1881 England census. Possibly the same person.
But here's an interesting twist. While scanning other England census years, I discovered numerous people born in Cleator Cumberland. I hope this doesn't confuse the issue.
But, like Rose, if you could provide further information about her, it might help others help you.
Cheers, Colin
