"Posie" the same as "Pazya Saggie"

I added the name "Posie" as per a family tree that my mom Ziva obtained from Stanley Tulchin (z"l), which shows her as one of two siblings of my grandmother, Naomi the other sibling is simply listed as "brother died in Russia 1974".

Is this name equivalent to "Pazya Saggie"? Please feel free to merge them if this is the case. Also, does anybody know who was the brother of Naomi that died in Russia in 1974?

I will upload the family tree drawing when I get a chance.

B'Shalom,

Tomer
