There is a school record for a Harriet Clare
Bath Street School, Islington
admitted 26.8.95
Clare Harriet, father John, 20 Peerless St, d-o-b 10.9.85
also (admitted same time)
Clare Elizabeth, d-o-b 14.9.87
Is that her?
Maybe ought to say that those birth dates in the school records aren't always right (or so I've found!)
