I don't remember anyone mentioning yodeling, but could be. I have a couple of photos of Nancy Hill, they are in bad condition. I have a photo of Jessie James Senior at age 56. Also have a couple of Jessie James junior, and of his brother and my grandfather Samuel Houston Butler. Also have some of their other brother, Doctor Tom Butler and his family members. Will be happy to email them if you would like.
Enjoy conversing with you, have a great day.
