Hi Pat, I didn't have time yesterday to copy out the census entry for William Callister & his parents - had planned to attach an image downloaded from Ancestry but that didn't work! Anyway, here is what it said:

1911 census: Home Leigh, The Village, Michael (ED15/2)
8 rooms
Thomas Callister head 54 mar. Engine Driver, Agricultural Threshing Mill. Born Michael, speaks English
Emily Jane Callister wife 56 mar. 28 years, I child born, 1 child alive. Born Malew, speaks Eng
William Callister son 27 single, Engine Driver, assistant. Born Michael, speaks Eng

Then Lawson's microsite has William's birth:

CALLISTER, William, birth reg. 7 Jul 1883, Michael 24 s/o CALLISTER, Thomas & CORRIN, Emily Jane

This could possibly be the burial of his parents:

CALLISTER, Emily Jane, 62, Michael 16 Jun 1916
CALLISTER, Thomas, 63, Michael 16 Feb 1919

There also seems to be a Will for that Thomas Callister: CALLISTER, Thomas 1919 Michael ref.91
