Welcome to the Archive of the Thienemann Family!

This genealogical archive is based on the works of Heinrich Gottfried Thienemann (1735-1793) and Otto Wilhelm Thienemann (1859-1941). The records include families that have married into the Thienemann family. This has been a collaborative effort over many years. We welcome you to our shared history.

Our Ancestors


The Story of the name "Thienemann"

The family name “Thienemann” originated as the surname “Duhnemann”, which then over time became “Dienemann” and finally “Thienemann”. The family name in German is spelled with two final “n’s” — many in our family in America go by the spelling “Thieneman” with one final “n”, the anglicized form of the name (a change that happened to many European immigrants when they came to America). But we are all of the same family.

There are 1,328 people born Thienemann or Thieneman in the Archive: 1043 born with the spelling "Thienemann" with 289 alive and 285 born with the spelling "Thieneman" with 218 alive. So as of today, the Archive knows of 507 people living worldwide with the name Thienemann/Thieneman.

The oldest known ancestor of all of these family members is a man named Nickol Duhnemann who was born circa 1526 in Holzkirch, District of Upper Lusatia, Bohemia — this is now Koscielnik, near Luban, Poland. And no, the family isn’t Polish — that region swung back and forth in control of different empires, hence the Germanic named city of Nickol’s birth. There are 1,263 descendants of Nickol Duhnemann on file in 14 generations.

In the words of Otto Thienemann from his 1933 genealogical work, “Genealogy is a science that is very close to us, because it contributes to awakening and deepening our love of our homeland and our attachment to our family. Our family tree should therefore not only satisfy our curiosity about the lineage of our ancestors, but also stimulate reflection. It must become clear to everyone who seeks to recognize himself that many of his peculiarities and also essential aspects of his character are 'in his blood' — or are innate. Thus, our self-knowledge includes - in addition to listening into our own souls — researching the way of life and destinies of our ancestors.”

An Archive such as ours is not static — it changes daily as new information is discovered. Your help in this is vital. Any assistance you could provide in documenting our shared genealogy would be appreciated.

Recording the Memories

The Ancient Egyptians believed we all die twice. First, when we take our last breath. Second, when our names are spoken for the last time. Remember that every time a person dies, it is as if a library has burned down. This is why recording family history is important. Help us save your family's history so that the future may learn from the past.

Every family has a story . . . welcome to ours.

The family genealogist

My name is Keith Thienemann, the genealogist of the Thienemann Archive. I was born in New Orleans in 1958, a member of the Louisiana line of the family. I've been working on our Thienemann ancestry since the 1970's. When I was 20 I traveled behind the Iron Curtain to meet our Thienemann relatives in Budapest, Hungary and filmed Otto Thienemann's book, page by page, on a window sill. Over the decades I have travelled and met with scores of our relatives who provided me with records, photographs, stories and hospitality. I was fortunate that I could do my genealogical research during my work as a professional photographer and choral singer. Now retired, I wish to leave behind this record for our future generations to read, learn, and enjoy. The work continues to this very day and hopefully you will join me in recording our shared history.
