Marny was born in Toronto, Canada and moved to the United States when she was 16. She and her family currently live outside of Richmond, Virginia. Marny started doing her husband’s family tree in 2014. In early 2016, she started working with a group to help people put the pieces of their puzzles together. In August 2016, she learned how to use DNA to help those with misattributed parentage locate their biological family members. In April 2020, one of those cases lead her to Father Founded, where she has been volunteering to help Amerasians with their quest to know their birth fathers.
