There was no formal adoption process in the 1800s. Orphaned children were often taken on by relatives or neighbours and sometimes are found listed as adopted child in the census. There might be a record in the Kirk Session Minutes if the session was involved in providing parish relief and/or finding a home for an orphan.
FamilySearch has a James McDonald born Old Machar 1837 to George McDonald and Margaret Smith, but James McDonald or MacDonald is a fairly common name so quite a few of that were name were baptised in that area at around that time.
