Hi Mark again!
And this, I beleive is Mary Elizabeth ADDEY his wife, in the 2 relevant UK Census before they married:
1891 - Blackburn Lancashire
Ecclesiastical parish: Holy Trinity
Ref: : RG12/3395 , Folio: 66, Page: 33
35 Hannah Street
Head: Seth ADDEY age 40, Tailor, b Pontefract, Yorkshire
Wife: Catherine ADDEY, age 34, Can Breaker?(smudged), b Prescott Lanc.
Son: Edward ADDEY age 15, Can Breaker, b Prescott, Lanc.
Son: John ADDEY age 8, Scholar, b Blackburn Lanc.
Dau: Mary Elizabeth ADDEY age 5, Schoalr, b Blackburn.
Boarder: John MACK, marr, age 52, Tailor, b Manchester, Lanc.
Note: Edward must be the brother-in-law, referenced by Cornelius in the 1912 Ship Manifest.
1901 - Blackburn Lancashire
