I'm more than willing to share what little info I have.
I'm not familiar with the names Ghaile, Myrtle May, or Rippeon but that may not mean anything. When I get a chance I'll ask my mother if Paul had any brothers or sisters by those names.
I do have some citizenship papers on Emanuel Etzler who I believe is Paul's father. I think he was born in 1861. The papers indicate that he became a US citizen in 1906 and lived in Texas for 1 year and the US for 5 years prior to that. His wife's name was Emma.
From what I understand the Etzler's in my family came to Texas directly from Germany.
