Thanks everyone!
talesofthesevenseas (love the name) - yes, I'm on facebook so will do as you suggest - many thanks for your input. And glad you like the photo
Frogpatch, I hadn't thought about it being a uniform of some kind but that makes a lot of sense!
greenacres, I'm going to keep the card but a rough value is very welcome

mart, the older children look like boys to me but the outfits are quite feminine aren't they? I think the Victorians often put boys in dresses but they were usually younger than this (so I guess the baby could also be a boy). It's very dark at the bottom of the image and I've tried to lighten it but can't see any real detail.
