(Correction to my post above, reply #18: Maria’s height was 5’7-5’7 ½).
You aren’t off-topic since you’re also referring to the height ; ) Btw In European metric system, Tatiana will be 1.75-1.76 m while Maria will be 1.73-1.74 m.
Tatiana and Maria were tall because of their genes. The Romanov dynasty is almost German due to marriages with German houses, starting with Catherine the Great. And I think Romanovs from the 17th-18th centuries were also tall ones, so Russian blood + German blood = more genes for tallness. Their mother Alix was also tall, the same height as Maria. Although Nicholas (1.68-1.70 m) cannot be regarded as a tall one on their standards, his father Alexander III was a tall man (1.64 m or taller). Their grandmother Maria Feodorovna’s Danish family also has tall ones, (even though MF wasn’t considered tall).
They could all be rough or what is considered "girly" at a given moment.
I think all of us (girls) are like this, too, depending on the circumstances. No matter how feminine we are, we can also act like a man—which proves that God created men & women equal : )
