Thhe Firs was used as an overspill from Poole Maternity Unit. This was from at least 1962.
I thought I should mention that during that time, pregnant unmarried girls of Poole, Bournemouth and the general district, were shipped off to Salisbury Mother & Baby Home. An attempt at avoiding scandal and give some kind of anonimity. They gave birth to their babies at Odstock Hospital, had to return to the Home for six weeks until their babies were adopted. It is feasible that a Mother with a baby born at The Firs, would then be moved to Salisbury ?
