Hello, not sure if my Sturza's had any family in the area you are researching, but I have info on Sturza's in Paltinossa, Bukovina, Austria as well as Gurahumora. Don't know if this is helpful to you, but I am also researching Sturza in the general areas of Moldova, Romania, Austria, etc. Also looking for any connection with Judaism in the Sturza family. Don't know if we are looking in to the same family line, but thought I'd take a chance.
Thanks!
