Thanks for the advice. For the record, I did the following, which seems to work.
1. Add the wife to the husband (since I already had the husband). 2. Add the son as an unlinked individual. 3. Add a mother to this child, linked to the existing "wife". This produces a second "marriage" for the wife with an "unknown" "husband". 4. Focus on the husband and wife and add a child, linking to the adopted son. This gives an "He already has parents" which I ignored. 5. Still focussed on the husband and wife, change the "relationship to father" to adopted and "to mother" to biological. 6. Add notes to say this is speculation and needs more research. It is possible that the adopted son was the legitimate child of the wife's brother (who has died, moved abroad etc.) so I really need to work in this later. Once more unto the to-do list I go.
