Gus Meade (Country Music Sources) cites
WCS#24(Oct. 1889), p. 17, 'A Lady In Love'
in connection with "In the Bright Mohawk Valley," etc.
"WCS" is Wehman's Collection Of Songs (NYC: Henry J. Wehman, 1884-94), 42 issues.
When I enquired of the Music Reading Room, Library of Congress, last year, I was told that Wehman's Collection of Songs was temporarily unavailable and that I should renew my enquiry after the new year. I did so. Sadly, I have now been informed that WCS #24 (Oct. 1889) could not be located and that "A Lady in Love" appears to be absent from all of the Wehman collections held by the LOC.
