Yet another Archibald HENDERSON

GenesReunited has come up trumps with a new Hot Match.
A new contact showed up with a match on Archibald HENDERSON & Agnes TODD. Although she isn't a relation, I now know a bit more about what happened to their son William, last seen as the informant for his wife Marion Glen HENDERSON nee AITKEN's death in Glasgow in 1908, and before that in Torpichen in 1901, with three dtrs, Ellen Haddow K, Amelia and Marion.
At the time I couldn't find William's death, bit too hard to pick which he was likely to be. The GR contact, Moira, had a year, which I've now confirmed, and found that the Procurator Fiscal got involved as the cause was expanded from the medical diagnosis on his death cert to include the information that the injuries were "by accident received through fall of portion of wall of shaft in colliery". So I guess there was a colliery accident in Bothwell around Dec 1925/ Jan 1926, his spinal injuries being of 8 months duration.
Couldn't spot a fatal accident report on the excellent Scottish Mining Villages web site.

Found dtr Marion's marriage, to yet another LAPPIN, which seems to not be as unusal a name as I thought, as I found when I did an index search for likely births following the 1917 marriage and quickly gave up on that idea.
Another branch of the HENDERSON family has a LAPPIN, but without a lot more work, I cannot see any immediate connection.
William's second marriage (1919 to an Annie HALLEY nee CAMERON) appears to have produced yet another Archibald HENDERSON for the files, another second cousin once removed to be found.
