my mum was born in rinteln germany 5th april 1960.
why we confused as family secret to who her father was and what secret about her birth.
she was born in military camp when her supposed father served royal air force.
she has two birth certificates with different information.
two different birth registered dates one was 1 year later, and two different father rank signed as notification.
Where can we find out her true birth record and information on this matter?
