IGI has an extracted entry for ANN CLUGSTONE Christening: 24 DEC 1854 Kirk Rushen, Father: WILLIAM CLUGSTONE, Mother: MARGARET WATTERSON, who fit the ones in the 1881 census, and her marriage in Liverpool.
There are 8 children in the IGI for this couple.

The IGI has a Robert CRELLIN Christening: 30 JUL 1854 Arbory, Father: JOHN CRELLIN, Mother: ESTHER COSTEAN, but I can't tell whether he is the right one among several Robert Crellins until his father is known.

In the 1861 Rushen census his mother Esther Crellin is Hd, wid., 44, ag. lab., son Richard Crellin 13 Lab Ld? Mines, Daur Jane Crellin 9 scholar, and Robert Crellin 6, all b.Arbory.
