I have found the Edward Langford Jones who married Jessie Ann on the 1901 and 1881 Census in Wales.
First, he is not the ELJ who died 1940 aged 89 i.e. bc.1851.
Edward Langford Jones married Jessie Annie Stephens in 1897 Forden, Montgomeryshire and Sarah Elizabeth Corfield Dec.1909 Forden, Montgomershire - however, he was born in 1871 (not 1851).
1901 Census - Argoed Farm, Churchstoke, Montgomeryshire, Wales
Edward L. Jones 30 Farmer b. Churchstoke, Montgomeryshire.
Jessie A. Jones 25 b. Chirbury, Shropshire
Richard C. Jones 3 b. Churchstoke
Jessie M. Jones 1 ditto
Margaret Jones Servant 16 b. Bishops Castle, Salop
John Parry ditto 21 b. Chirbury, Salop
Robert E. Jones ditto 20 b. Churchstoke, Mont.
Charles Jones ditto 16 ditto
ref. RG13 5199 30 6
1881 Census - Pentre, Churchstoke, Montgomeryshire, Wales
Richard Jones 44 Farmer of 130 Acres employing 3 labourers
b. Bettws, Montgomeryshire
Elizabeth Jones 42 b. Berriew, Mont.
Edward L. Jones 10 b. Churchstoke
Emily M. Jones 3 b. Churchstoke
There was one other marriage for an Edward Langford Jones - 1869 Montgomery, Shropshire plus the 1861 Census for Oswestry, Shropshire shows an Edward L. Jones, nephew to a Charles Carrington and family - he was 10 and born Newtown, Montgomeryshire, Wales - possibly the one died 1940?.
Certainly, the one who married Jessie/Sarah was born 1871.
Whilst I can't provide the link you seek hope this clarifies who the Edward Langford Jones was who married Jessie and Sarah.
Good luck.
