Sarah SIAR born c1835 Lydney (General)
I think this may hopefully be of use
1871 census, Warrington - District St Paul page 24
Thomas BURTON - Head age 31, Iron Worker - Metal ......born Fradswell, Staffordshire
Eliza - wife - age 27 born New Bridge Glamorganshire
Thomas BURTON married Eliza SIRE - June 1864
So I think this is Sarah's, William's and Thomas - sister
William - Son age 5 Scholar, born Lancashire, Warrington
Thomas - Son age 4 born 'ditto'
Ceclia - Daughter age 2 - ditto
and then we have
William SYAR - Boarder - unmarried age 25 Iron Worker Forge Roller born Worcs Stourport
