I am looking for the child of Meta Schleicher and Kaarel Siniveer (Schleicher) (born 1906). I am the daughter of Kaarel Siniveer (born 1947) and he met a woman claiming to be his half sister in the 90ies in Tallinn. We lost all contact and information about this woman. I only remember her name was Sirje (but not sure). Is there any chance of finding something about her? I am in Germany and don't speak much Estonian (only learning).
