Family History - O

OBISPO
I live in Spain, my father Alfonso Obispo was born in Walthamstow in 255 Brettenham road the fifth of August of 1906, his father's name Roberto Obispo , his mother's name Harriet Obispo formerly Bishop, date of registeration 19th of September 1906 the deputy register Cistie Write (more or less). Application number S.R.22972/30. There is another sister Rosina born the 24th of August of 1905 registered by secretary Jackson. I give this information because I think there is another girl and I know nothing about my English family. My father came to Spain in 1912 I do not why - may be his parents' death, but only my father and Rosina came and if another dauther existed she remained in England. I do not why. My father was 6 years old and he never told us about his family, He was adopted by a Spanish family but they didn't change
his real name. I would like to know something about this part of my family, thank you. Estella Gomez email
