The Family SAINT-GERMAIN is orriginated from FRANCE where Jean de Saint-Germain married Rosa de BRETON and came to GALICIA - Spain (Ferrol) in 18º century where the family´s name was changed into SAN GERMÁN (in spanish).
Then, some members came to Portugal (Caldas da Rainha) and the name was once again changed into SANGREMAN (in portuguese).
Maybe some member´s family imigrate to some english speaking country and the name perhaps could be changed over again !
My grandfather was born in Portugal and then came to Brazil where he died.
If the families were related I would like to receive a message to the following e-mail: email@example.com
(forgive my english writing...)
