Have you DNA tested Sylvia? I "suggest" testing with both FTDNA & Ancestry. If you can afford it, test full sequence mtDNA. Upload your results to GEDmatch (which will match you with DNA matches from any testing company who also upload. I am an adoptee. In fact, you are 2 days older than me. I have now found both my maternal and paternal lineage. I had a DNA match with a paternal half-brother last year. Neither family cares or is social, but now I know my nationalities and I'm working on my trees, which is very satisfying. My non-identifying information wasn't accurate so now I know my true ethnic backgrounds. Good luck.
