Ok, thank you. I'm sorry if I'm asking stupid questions. I've always supposed it was in Peterhof, but then, I wasn't sure, because there's an extract from Nicholas' diary from May 15 and they're still in Tsarskoe Selo. I just started to wonder if they had moved from a place to another, the birth being so close...Was it a Lower dacha where Tatiana was born (and Maria, Anastasia and Alexei too?) Do you know when Tatiana, Maria and Anastasia were christened?
