https://www.rootschat.com/forum/index.php?topic=832009.msg6965714#msg6965714The 'missing' marriage isn't really a Presbyterian query but a general one. However, in this case, after checking Scottish, English & Welsh records (the last 2 unlikely but easily checked), if nothing turns up I don't think there was a marriage between William J. McComb and Ellen.
Does the report of her suicide shed any light on whether she was married or cohabiting at the time of her death (either might, according to wording of late husband's Will, mean that she would not be entitled to his property, etc.).
What about any mention of legal proceedings in newspapers prior to her death?
I'm starting to think this person could have married his aunt (through marriage - widow of his blood uncle).Why do you think he married his uncle's widow? From the other thread-
William McDowell married 1863 Eliza Bean (age 18). William McDowell died December
1878. Eliza died (as wife? of W.J. McComb) in 1881.
Thus any 2nd marriage for Eliza would have been Dec.1878-1881. William John McComb was about 22 in 1881. If they got married before around 1880 then he would have been under age which might also explain why they never actually got married.
