THANK YOU Patricia and David !!
Using those clues and facts I found I do believe Laura's parents in Cherokee Co, TX, 1880 .. on her FaG memorial, connected to Henry's FaG memorial, it says in text that her father was R. P. Musick.
Figured Robert, RIchard, Randal ...um. He was born in Louisiana according to the census for Laura ... and experience tells me we will include Ransom, popular name in Mississippi and Louisiana ... and there he is, the family, in Cherokee Co, TX, Ransom and Henrietta Music (no 'k')
"United States Census, 1880," database with images, FamilySearch(https://familysearch.org/ark:/61903/1:1:MFFY-N6J : 15 July 2017), Laura Music in household of Ransom Music, Precinct 3, Cherokee, Texas, United States; citing enumeration district ED 14, sheet 354D, NARA microfilm publication T9 (Washington, D.C.: National Archives and Records Administration, n.d.), FHL microfilm 1,255,295.
Clicked on HIS name, and it's Ransom Pinkney Musick 1852-1925; wife is Henrietta Lenora AVERY, 1856-1934
Oh, there's a lot of profiles to be done, parents and siblings of both Henry and of Laura
