Hi Esilda. What I have on the Amador and Barril is little mixed up but I believe that you are related to my wife's side of the family. The names match up what little I have. There is another relative in Florida that I can go to but I haven't asked Carmencita to clear this up since I am working on other roots.
Here is what I can share feel free to email me personally to continue corresponding.
Damian Rodriguez/Manuela Barril- M abt 1850. child Andres Rodriguez Barril 12/11/1871 Santurce, PR -June 30, 1957 San Juan, PR. But I have some notes that says Rafael is father of Andres so I am not sure of this name.

Andres married twice -first unknown, 2nd to Carmen Barril abt 1903. Carmen born Abt 1882 in Arecibo. Died Oct 7, 1946. They had a large family of seven. Augusto, Zoraida, Gilberto, Carmen, Andres, Daisy, and William. Augusto was a chorus director in the UnivofPR. Zoraida married my wife's grandfather Luis Domingo Font Carbonell.
I do have Jose Amador and Carmen Barril as parents of Carmen Barril abt 1882. That is the only child I have but I think i had see Ana Amador somewhere is the census and wondered if she was related.

I would like to share more information so let's continue emailing. Where do you live? This is great!
