Got the Swan line back to the mid 1600's (plus the line of Florence's natural father back to the mid 1500's). It took a bit of digging, plus some lateral thinking to throw up all the connections, but I've had the 'missing links' and some romances on both sides of the counterpane verified by others.
It's Peter Walker's ancestry that is proving difficult, and that is where being able to track down a death certificate would help -- His marriage certificate does not give many clues, Age at marriage given as 23. Father's name given as John Walker, mariner.
Lowestoft census records show that he was a fisherman, originally from the Liverpool area, but I've not been able to tie any available birth records to him.
From FreeBMD
A Peter Walker is registered born Liverpool, spring quarter 1858 -- Possibly born June 1858
Date of and place of birth estimated from marriage details (certificate obtained).
A Birth Certificate obtained for Peter Walker, b 12 May 1858 - father name given as Joseph Walker - Shoe Maker -- does not appear to be correct Peter.
1861 census at private house, West Derby - Boarder - the only Peter of correct age in Liverpool area. It is possible that his mother had died whilst he was an infant, and as his father would be away at sea, he was 'boarded' with another family - possibly a relative.
1871 census - the only entry of correct age is located at 80 Roper St, Whitehaven - apprentice draper - pob Liverpool, however at age 13, Peter may also have been away at sea as by then he was of working age. Another possibility was that he may have subsequently left the draper's trade, and become a fisherman - Whitehaven being an important fishing port on the West Coast
1881 Census In port -- Lowestoft harbour -- on board fishing vessel "Sea Flower"
Herbert SANDWELL M 24 M Broadstairs, Kent, England Master
William WRIGHT U 19 M Carlton Colvill, Suffolk, Eng Mate
Peter WALKER U 21 M Liverpool, Lancashire, England Seaman
George LONG U 17 M Carlton, Suffolk, England Apprentice
William LONG U 14 M Lowestoft, Suffolk, England Apprentice
Married: 31 MAY 1882 to Florence Gertrude Swan in St. Margarets, Lowestoft, Suffolk - Occupation - Fisherman
Note: Note: Witnesses: Charles Calver and Elizabeth Rose Britteon. Elizabeth Rose Britteon was Florence Swan's half sister
Date of Death approx 1915 taken from an entry in the IGI, However I can find no record on Free BMD, or in Military records - however as he would have been 56 at the outbreak of WW1 it's doubtful whether he would have been in the Royal Navy.
The Lowestoft fishermans memorial does not list him as having been lost at sea.
Any help greatly appreciated.
