MariaCafferty on Family Tree Circles

I am from Brazil. I graduated in Medicine in Brazil and went to the USA for postgraduate studies. Returned to Brazil to teach at the University, married and Englishman and here I am in England for the past 44 years. I worked in NHS for 44 years, the last 12 in the Prison Service. All my relatives have died, I know few bits of the family history.

my great grandfather immigrate to Brazil in th 1800. He went to live in the northeast of Brazil near the capital of Maranhao, S. Luiz. he was a farmer, apparently had a big farm with slaves. One son and one daughter. His son died as a young man, the daughter did not inherit the farm. Would like to know where he came from.
