Your grandmother, Patricia Baptista was the first cousin (and maid of honor) to my mother, Rosalie Baptista Abreu. My grandfather, Frank Baptista, was Juan, Pat's father's, brother. Evalena Baptista was my mother's aunt..
I have information one generation further back than you have. Jose's father was Joe Baptista and I have been told that he was of English descent (the origin of the blue eyes in that family). His mother was Catherine Souza.
Rose Emelia Silva's mother was Riosa Imilia (last name unknown) and father was John Silva.
I do know that my grandfather and great uncle John's (your grandmother's father) had a sister Mary or Maria that remained in Castelo Branco, but I didn't know if all of the brothers that immigrated were from that village or from the city of Horta.
Please contact me. I do have some other information, but not much.
