“I engaged Carol on a project to identify living cousins who are genetic carriers of a rare mitochondrial disease called Leber's Hereditary Optic Neuropathy (LHON) that passes from a mother to all of her children and can cause sudden-onset legal blindness.  She built out mitochondrial trees for several families carrying a LHON mutation, identified all their living mitochondrial cousins including contact information, and provided guidance on how to do the outreach.  Her reports made everything clear for the participating families and she delivered helpful strategies on how to make contact with warmth and the confidence that comes from deep experience.  

Carol developed a comprehensive presentation about the project and delivered it at our recent LHON Conference to educate and inspire other LHON families to do their own genetic genealogy projects.  Carol was a perfect fit for this endeavor as she is clearly passionate about her work, meticulous with her research, a master at finding living individuals, and an extremely effective communicator. 

I wholeheartedly recommend Carol's services to others who have similar projects, and to anyone seeking a collaborator in applying genetic genealogy in innovative ways.”

“My mother was a foundling, with no knowledge whatsoever of either of her birth parents. I had her submit a DNA test through Ancestry.com about a year ago and began doing some research on the list of DNA matches that appeared. On my own, I was just not able to make much sense of the long list of DNA matches. I decided to hire a professional and called Carol.  The outcome was amazing! In about a week, Carol had found both my mom’s birth mother and birth father, along with three living half-sisters and a half-brother as well as other birth family members. She completely solved a life-long mystery (my mom is 83) in a flash! I am absolutely amazed at how much information Carol was able to find.  Carol is lovely and pleasant to work with and her fees are very reasonable. I can’t recommend her highly enough!

"I was referred to Carol Rolnick to help me with DNA research--and I'm certainly glad I was!  Just some of her great attributes were her research knowledge base, her friendliness, and her understanding of DNA. She kept me updated on a regular basis, including personally calling me on the phone to let me know when she had found my biological father's name.  I really appreciate everything she did, but most importantly for me, she was extremely thorough and competent.  I can't thank her enough for her kindness and help!  If anyone wants to hire a DNA genealogical researcher, I would very highly recommend Carol Rolnick."

Testimonials & Case Studies

"I discovered through DNA testing that the father who raised me was not my biological father, and I worked with Carol to help me identify by bio-dad. She made sense of my complicated DNA results, and she was able to pinpoint my bio-dad so quickly!  She also turned my mixed emotions into appreciation for my bio-dad. This well-kept secret turned out to be a vital aspect of myself, and the similarities are amazing. My life has been greatly enriched through new relationships with my biological family. Thanks Carol for ALL you’ve done to help me through this journey of discovery.”

“I am an adoptee and I did DNA testing in hopes of finding my paternal side.  After working with my results for about a year on my own, I decided to get help.  Carol came highly recommended by some of the leaders in the genetic genealogy community, so I was anxious to work with her. The whole experience with Carol was professional, thorough, quick – AMAZING. She kept in close contact by phone and email and before I knew it she had confirmed my paternal line!  I asked her to make contact with my first cousin, and she was gentle & discreet. Her knowledge of DNA and genealogy is truly outstanding.

I can't THANK Carol enough for finally closing this chapter in my life. I now am in contact with my half-brother and cousins and have traveled to meet them as well. I highly recommend Carol to anyone searching for unknown family.”
