Hi!
The baby has been labeled as
Anastasia?! That's weird! I'm sure it's a mistake. I think they were different photoshoots took at the same place over the years. (Where is it, by the way?)
Obviously, these are from the same photoshooting. There's also a pic of Tatiana, but I don't have it. Olga and Tatiana look pretty young. So I always thought the baby was Maria. If you compare well-known pictures of the Little Pair, you'll see their faces were quite different even as babies. I think those photos were shot in 1899-1900.
Look closely at this one. Names have been written under each girl in our handwritting, from left to right: Olga, Maria, Tatiana. And the legend under the photo lists the girls as the three oldest, too. (I suspect it was a postcard.) The date says 1903. It could make sense, but I'd go for earlier years, given the fact that Maria is dressed as a baby.
Then come these, photos from a while later. Maria looks slightly older, doesn't she? I'd say it's from 1901.
Finally, I've also found this shot. Not the same coats, so not the same day. And Anastasia can walk here, so it has to be at least in 1902. Here fits the one with Tatiana in her pale coat, standing in front of a tree. Which palace can be seen behind the girls in the second one?
I hope it'll help. Maybe I'm wrong for the dates, but I'm absolutely sure about who's who.
