My dad's cousin was born in 1905 and although both parents attended the registration of her birth she was marked as "illigitimate" according to the law in those days. They eventually married in 1908. There was no legal reason for the parents not to gave married before her birth as both were single although very young.
Her birth was re-registered in 1947 - 42 years later. Never found out why.
