Just saw you message and thought i would take a chance that this is the same erdal family farm that my family comes from. My grandfather Jorgen Jorgenson Erdal (Erdahl) came from the Erdal farm in norway by Stryn.
Song og Fjord i believe is the county or area. Along with many other ancestors, I have always wanted to visit that farm and would love to see pictures of it old and new.
My grandfather was born on February 19, 1883 and his parents were Jorgen and Johanna (Bodal) Erdal.
Let me know if there is a connection at all
cant wait to hear from you
