Hi,
I think Sarah remarried,
Sarah KIRK Jun Q 1887 Dewsbury 9b 1013
Mary Jane RICHARDSON
Thomas BEAN
Eardley SWITHENBANK
In 1891 Eardley SWITHENBANK is married to a Mary Jane, so it looks like Sarah KIRK married Thomas BEAN.

Living in the household of Hannah GLEDHILL

Caroline " Wife M 57 " Morley
Sarah BEAN M-in-law Wid 77 " Beeston
