Adopted Friends Discover They Are Biological Sisters via DNA Test
Meena Geltink, 43, and Minal Tijssen, 44, discovered through a commercial DNA database match in April 2026 that they are biological full sisters, having met three decades prior as teenagers at a gathering for adoptees and maintaining a lifelong friendship without knowing their shared parentage, according to reporting from NOS Nieuws and RTL.nl.
As commercial DNA databases process millions of profiles annually, enterprises face mounting compliance pressures under frameworks like the General Data Protection Regulation (GDPR) to safeguard sensitive genetic data.
The Decades-Long Connection Across Dutch Provinces
The narrative began in 1996 when Geltink and Tijssen crossed paths at an event for adopted children. Both women had experienced difficult early childhoods in Indian orphanages before Dutch families adopted them, raising them roughly 130 kilometers apart in the Dutch towns of Wilp and Made, per RTL.nl. From their earliest interactions as teenagers, the pair noted striking physical similarities. Geltink recalled peers pointing out identical smiles, noses, and eye structures. For amusement, the two began addressing each other as “sis.”
Despite living in separate provinces, an immediate and intense bond formed between them. They regularly discussed careers, studies, and personal milestones as their friendship matured. Tijssen eventually relocated to France, and while contact became less frequent into their twenties and thirties—with a notable exception during Geltink’s pregnancy around age 28—the underlying connection persisted. Neither woman possessed documentation linking them to biological relatives prior to the recent genetic testing results.
Commercial DNA Databases and the April 2026 Breakthrough
Geltink actively pursued her Indian roots from a young age. In 2017, she uploaded her DNA profile to MyHeritage in an attempt to uncover familial ties, yielding only distant third- and fourth-degree matches such as second cousins, according to RTL.nl. The breakthrough materialized in April 2026 when Tijssen registered with the same commercial database. Weeks later, a notification appeared on Tijssen’s mobile device displaying Geltink as a full sibling match.
Tijssen immediately contacted Geltink via Facebook to share the results. Geltink, who had previously deleted the MyHeritage application to free up device storage, reinstated the software to verify the match. Following the digital confirmation, the sisters arranged an in-person reunion in Den Bosch alongside their partners, marking their first gathering since the genetic disclosure and ending a fifteen-year span of limited contact, as detailed by NOS Nieuws. While acknowledging the missed milestones of their youth, both women expressed profound relief and happiness at reclaiming their biological relationship.
