11th: This is so much more fun than work

Back to the New York FAIRBAIRNs of Delaware and Ulster Counties. While trying, still unsuccessfully, to find Lucia FAIRBBAIRN, dtr of John Francis, aka Frank, FAIRBAIRN and Delilah in 1910 and 1920 I stumbled across an instance of a chap recorded twice in the 1920.
Hillis FAIRBAIRN shows up once with Frank and Lucia (AVERY) FAIRBAIRN as their unmarried son working on a railway section (census taken 22-24 Jan). With the next entry being the widowed father of his wife Olive.
And also, on 25 Jan 1920 at home with his wife Olive and son David J FAIRBAIRN, enumerated as FAIRBEN with occupation as laborer Nth D? Section.
Lucia was subsequently found when it was pointed out to me that I'd misread her birth date in the census. Once I'd corrected that, things fell into place rather better, even if she was enumerated as Lutia A and indexed as Luter in one of them!
Updates to the published info will follow in due course.
