She found me after taking the test herself looking for her (our) paternal linneage. A not too distant common relative did the 23andme too and a little detective work in online obituaries was all she needed to find me. Strangest FB message I have gotten to date. I thought she was a cybersecurity recruiter as I noticed she was looking at my LinkedIn profile a few days prior to contact.
I used to be more concerned about the privacy implications. Maybe it's my age or something but I feel at peace with my choice. Besides I realized once one somewhat close relative is in the database it takes very little to link us all up.
Was it worth it all things considered? For me it was though without the desire to confirm our relationship I probably wouldn't have done it.
