She had made Lancaster her home for the past decade, drawn by the amenities of Willow Valley, proximity to family, and the serene Lancaster County countryside. Friends and family often visited, enjoying scenic drives through rolling hills and outings to the local Amish farmers market.
Dorothea engaged with the community through Willow Valley’s lecture series and musical performances, forging new friendships. She volunteered at the Willow Valley post office and eagerly participated in pop-up bridge games.
A native of Pennsylvania, Dorothea was born on October 11, 1927, in Philadelphia, the eldest of six children to John and Alli L’Tainen. She embraced her Finnish-American heritage with a deep sense of family and cultural pride, embodying the traits of the Finnish "Sisu," best known for its stubborn resilience and determination. After graduating from Philadelphia High School for Girls in 1948, she pursued higher education at West Chester State Teacher’s College, earning a degree in early childhood education in 1952.
As a working student at West Chester College, she had little personal time. The silver lining, however, was meeting her husband-to-be, Kenneth Malcolm Merz. This event occurred during a lecture where a frog got loose in the classroom. Being a city girl, Dorothea jumped on her chair, frightened of the wayward frog. Kenneth was astonished, and he took it upon himself to help her overcome her fear of frogs. Soon after, they were married on June 28, 1952, and enjoyed a long and loving 54 years of marriage until Kenneth passed away in June 2007.
During those earlier years of marriage, Dorothea spent her time as an elementary teacher, later becoming a stay-at-home mom in Malvern, Pennsylvania, happy to raise their four children: Kenneth Jr., George Jr., Andy, and Liisa, along with her beloved dog, Velvet, and a coop full of chickens and ducks. She found joy in gardening. Particularly, she loved cultivating flowers to adorn her home or as gifts for friends. Her plantings invited birds and pollinators to her carefully designed gardens.
Dorothea lived a life rich in diverse passions and deep connections. Her journey began with her love for music, lessons from a neighboring pianist, and later with more professional studies. She frequented the Philadelphia Symphony and local musical events and occasionally would sing along with operatic performances on her kitchen radio. She attended several piano recitals, performing compositions from Schumann and Mozart.
A lifelong learner, she loved literature, history, and autobiographies of the lives of worldwide luminaries. She read at a fantastic rate, routinely bringing 5–10 new books from the library on Friday evenings and returning them for another collection the following Friday. She was much appreciated for her literary knowledge! Instilling the love of literature in others, she always made time to read bedtime stories to her children and grandchildren.
Her interest in early American history, architecture, and antique furniture was a shared passion with her husband, who lovingly restored and cherished these items. Dorothea and Kenneth, with some participation from their children, worked together to restore a 200-year-old, beautiful farm home and barn in Gladwyne, Pennsylvania.
A deep commitment to community and service engagement characterized Dorothea's life. This includes volunteering for the health clinic in Phoenixville and other educational initiatives. She was an active member of the Questers Group and the Finnish Society of Philadelphia. Alongside her interests, she supported her children's pursuits by attending their events and celebrating family whenever possible.
Beyond her diverse interests, Dorothea nurtured meaningful connections with family and friends through decades of handwritten letters and cards. Her biggest delight, however, was hosting family Thanksgiving or Christmas parties and reunions, where her excellent cooking abilities effortlessly whipped up full four-course meals, sometimes spontaneously, for impromptu gatherings.
In later years, after becoming an empty nester, she attended St. Peter’s Church in the Great Valley, Malvern, PA, rekindling her spiritual devotion and partaking in community events like the knitting group creating prayer shawls. Her dear church and family were a source of joy and connection that lifted her after the loss of her son Andy and the passing of her beloved husband Kenneth.
Dorothea took immense pride in her family, celebrating their achievements and nurturing deep bonds with her grandchildren, nieces, nephews, and friends. Her life was a testament to love, dedication, and generosity. Dorothea L’Tainen Merz will be dearly missed by all who knew her, and her memory will be cherished.
As her last act of humanity, Dorothea donated her body to the Humanity Gift Registry and will remain at the Hershey Medical Center until their studies are completed. This may take up to two years to complete. Future funeral and memorial arrangements will be made upon the return of Dorothea’s remains to her family.
Dorothea L’Tainen was preceded in death by her husband Kenneth Malcolm Merz, son Andy Arvi Merz, and sister Martha Ann Plankenhorn.
Dorothea is survived by her sons, Kenneth Malcolm Merz Jr. (wife Debbie) and George Lenard Merz Jr.; her daughter Liisa Lillian Lê (husband Hung); her sisters Dagmar Schilke, Linda Beuerle, and JoAnn Tate; and her brother, Don L’Tainen (wife Jolene). In addition, she is survived by four grandchildren: Charles Kenneth Merz, Margaux Ruth Merz, Jonathan Hunter Lê, and Trinity Elizabeth Lê.
