I have just found this information in the "Derbyshire Times" of 29 Sept 1950:
William James London (59), packer, 4, Appletree Road, Stanfree, leaves a widow, one son and one daughter. He was born in the house next door, 2, App letree Road, where his parents, Mr. And Mrs. F. London, kept a general store, now run by Mr. Brough. Mr. London, whose brother at Creswell was also killed in the disaster, had worked at Oxcroft and Whitwell Collieries, and had been at Creswell pit for four years. He was a member of Oxcroft Colliery Institute and of the Miners' Club at Shuttlewood. He had been employed as a collier for 45 years.
(NB the paper have got his age and length of service wrong)
and also this about is brother:
John Henry London (48), "The Dene," Skinner Street, Creswell, lived at Stanfree for most of his life, going to Creswell in 1938. He worked at Creswell pit for about 15 years and was previously at Oxcroft and Shireoaks. He was married with a son and daughter.
But still nothing yet to link William James to Frank Lesley.
(I have found John Henry's children on the BMD but none of William James)
I have also found out that his wife's maiden name was probably Partridge.
From the Derbyshire Times of 29 Sept 1950:
When Mrs. Tilda London. Apple Tree Road, Stanfree, arrived back from the funeral of her mother, Mrs. E. Partridge, Chesterfield on Tuesday, she was told that her husband, Mr. W. London, had been killed in the disaster.
I have looked on Ancestry's BMD for the first three quaters of 1935 and found no Frank Lesley Partridge but the last quarter is missing from the site. Can any one do a check for me please to see if there is a Frank Lesley Partridge in the DEC qtr of 1935. A long shot but you never know!
If anyone can help in any way, especially to link William James London to Frank Lesley London, it would be really appreciated.
