Would you purchase a birth cert for someone still alive? I have a mystery that can be solved by the purchase of the birth cert, but I do not feel it is ethical to do so. Briefly a 90+ (born 1920's) year old relative has a birth reg with the surname he uses and the correct mmn. On the 1939 reg the mother is listed as single living with her mother using her maiden name obviously her son's entry is still redacted, there is no redacted entry in that household. The surname of her son is added in green, onto the 1939, so a later entry. I cannot find any marriage after 1939 (nor before). The only person who might possibly be able to tell me the father's name (his 80 year old cousin) has no recollection of any father/husband, nor knows a christian name. There is no way I will ask the the chap concerned, so his father's name will have stay unknown. So would you buy the cert and keep quiet about it's content, or just leave it?
