I own the sister violin to the one that you described in you post. The maker's name is F.A. Sennet. My label reads:
Made for Marsh.Marley
Dallas, Texas 1919
I've owned this violin for about a year and have not found anything about Marsh.Marley. Sennet made a lot of fiddles and you'll find them scattered around here and there. I realize that you posted this 5 years ago, but if you happened to get this post email me at, email@example.com
I emailed you at the address you listed. Hope to hear from you.
