To Geoff and Kath,
Had a peek at FindMyPast and sure enough;
Elizabeth Altoft Head Married (husband from home) 61 born Lincs, W. Butterwick
Jane daughter Un 30 Lincs, W. Butterwick
Charlotte " " 17 " " "
Elizabeth granddaughter 6 Yorks, Thorne.
That's good enough for me, this is almost certainly the one born in the workhouse at Thorne. My Eliza Altoft is most probably in William's family living in High Street, Epworth.
With regard to death registered in Thorne Dec 1859; don't know, but obviously not mine as she lived to about 1898.
Thanks again,
Martin
