Hello, I am also looking for family with the name Sowikromo in Indonesia. My family tree stops with my grand mother, the mother of my mother. My grandma was kidnapped from Indonesia on her way to her shop on the market of Yokjakarta. She was sold to Dutch people and was transported to Surinam. In May 2006, my mom wend to Indonesia again with her brother to search for family. But with no results. Now I'm looking world wide for family but it's not easy. You're the first during my seach who is also looking for the same name. My mom has 2 brothers, one is very ill and my mom wishes him to meet family before he dies.
Did you find family with the same name in Indonesia? We now live in The Netherlands and from here we're searching further for our family.
We've aslo looked into the database of the National Archives and found a picture of my grandma. I sure do look like her...
