There were no formal legal adoptions in the IOM until
1928. Many families however did " take in" orphaned
children who needed a home whether related by blood
or not. In my family one child is actually listed with her
own family name & adopted [1901] which I think must be
unusual. It would have been more likely for her to be
using our family name at school & on the census &
perhaps reverting to her birth name by choice on marriage.
