Christiana appears in the 1881 Census at the age of 18 as a General Servant in the household of Joseph & Mary WARD at Alger Kirk & Amber Hill.
What the census image actually says - the place - Algarkirk Fen now Amber Hill.
Please be aware that there are two Kirtons in Lincs (both known as Kirton on censuses)
1) Kirton in Lindsey - where your lot were - 6 miles south of Scunthorpe;
2) Kirton in Holland - coincidentally, only a couple of miles from Algarkirk - 3 miles south of Boston.
They are about 55 miles apart by road.
