After a search today Ada Maud Rice Whitehead was the wife of Alfred North Whitehead who was born in Ramsgate (1861) died (1947, Cambridge, Massachusetts).
Ada Maud Rice née Willoughby-Wade was born in Honfleur, Calvados France.
Thankyou for your work on this subject, yet I would like to know more about the Willoughby-Wades in Ireland, if this is possible.
