My name is Seila Siric, I was doing some research on my family tree, and I might be able to help you. My mothers Maiden name is Raseta. the S does come with a "mark" on top. Originally my family is from Serbia, and we still have Raseta Family living, along with my Grandfather. idk how this may help you, but i can tell you that the family started in France a long time ago, the original name was similar but french, due to prosecution in france, a very great grandfather fled over to the Ottoman Empire along the slavic lands, and landed somewhere along serbia where he renamed himslef Raseta to go with his new home, yugoslavia. he married and had children. along the way many moved on and had families of their own in diff cities and towns. idk how much more i can help you, without you asking me i supposed. but neevertheless the family line started with 1 french man. along the line here we are decendants.
