I really enjoyed being around Ms. Dorothy. She was like a mother to me. I really enjoyed our weekly visits together.

Dorothy Luyster Siebert


Dorothy Luyster Siebert, aged 99, passed away on April 17, 2022 in Amelia Island, Florida. Born on July 5, 1922 to the late Katherine and Walter Luyster, she grew up in Sea Cliff, Long Island, New York.

After graduating from High School, Dorothy enrolled in nursing school in New York City and ultimately became a Registered Nurse. While in training in NYC in 1942, she met her future husband Robert John Siebert, who was training to become a naval officer. Thus began a wartime romance. Mr. Siebert’s destroyer (USS Mayrant) was damaged in an air raid at Palermo, Italy on July 26, 1943. The Mayrant returned to the United States for repairs, and the Sieberts were united in marriage on March 18, 1944 in Glen Cove, New York.

Mr. Siebert remained in service on the Mayrant in the Pacific until the end of WWII. He and Dorothy moved to Orlando, Florida where Robert began a career with Crown, Cork and Seal, a large packaging company headquartered in Philadelphia, PA. Over the next few years, the couple welcomed three sons, Michael (now deceased) born in 1946, Peter born in 1947, and Donald born in 1950.

While Robert was absorbed in his business career, Dorothy focused on raising three boys, and ultimately eight grandchildren and nine great grandchildren. She was the matriarch who taught her family the value of manners, hard work, and faith. There were many relocations which she managed wonderfully, amidst bountiful complaints from her children. After their first home in Florida, their marriage took them to Long Island, to Philadelphia, to Palo Alto, and back to Philadelphia.

They retired to Amelia Island, Florida in 1995 into a residence which became a magnet for family gatherings over the years. Robert Siebert died in 2018 at age 97. Their 74 year marriage is a source of inspiration for friends and family.

A service will be held at Amelia Plantation Chapel at a future date.

Donations may be made in Dorothy’s name to Amelia Plantation Chapel.
