Hi Danika, I was born in Beira, Sao Jorge, Azores.Am descended from Miguel Teixeira de Bettencourt and Barbora de Sousa originally from Rosais. I do not, however, have a Hieronymo nor a Jeronimo in family tree. Have you considered looking in the Rosais records? The people from those two towns intermarried often, at least in my family.
Am also a Breves. All the Breves of Sao Jorge are related. The original Breves to settle in Beira had two sons and a daughter, but, that I am aware none went by Bettencourt. Would like to know how your Christina (Rosa)Breves connects to my branch. Where did she get Breves?
