This is one of those posts, in fact. I've only encountered old-time banjo frailer Julie Duggan on YouTube, where she posts on the Knockdownbanjo channel; some wonderful music there (as you are about to hear), & also some nice mp3s on her website (link at her name.)
Beyond that, I know very little about Ms Duggan—she does have a teacher page at the Banjo Hangout, & my ears tell me that she’s a fine & spirited musician. Lots of really good musicians out there, folks: not all of them have record deals or touring schedules, but they’re all keeping us entertained & happy!
“Suzanna Gal” also goes by the title “Fly Around My Pretty Little Miss,” & is a standard old-time fiddle tune. It was recorded both by Gid Tanner & the Skillet Lickers & Frank Blevins and his Tarheel Rattlers in the 1920s string band versions. The tune was also recorded by Round Peak, North Carolina banjo wiz (& top notch fiddler) Tommy Jarrell. 
“Ladies on the Steamboat,” the second selection is a less familiar tune; it was recorded by the duo of Dick Burnett & Leonard Rutherford (better known simply as Burnett & Rutherford) who wielded the fiddle & banjo respectively & were stalwarts of early country music from the ‘teens all the way to 1950. They are now less well-known than contemporaries like the Carter Family, the Skillet Lickers & Uncle Dave Macon.
Hope you enjoy these fine renditions of two great old-time tunes!
