Alex, I might have originally gotten this information from you as Marion is only distantly related to my line, but I show a Marion Abercrombie as being born March 17, 1868 in U.P. Close, Kilsyth, Stirlingshire, Scotland.Her/his (?) parents were William Abercrombie, b. Oct 28, 1844 in Parkfoot, Kilsyth,Stirlingshire, Scotland, and Elizabeth Campbell, born 1846. These parents were married August 17, 1866 in Kilsyth, Stirlingshire, Scotland, in United Presbyterian Church.
Hope some of this might help you, though you are probably looking for information after she arrived in the USA.
