In the North Sea area our name was Jung, meaning young, youthful and brave. The spelling for the last part of the name has been translated in several ways, depending on the area where the records were found. "Blut" is one of the oldest ways of spelling it and means blood; race; parentage; birth-lineage. Thus, the meaning of the name Youngblood as we know it today is "young fighter of that blood line" and/or "brave youth of our race".

Some of the different spellings of the whole name are Jungblut, Jungblud, Jungblodt, Jungblodte, Jungbloed and Youngblud. As written records on most people were not kept, or were lost due to war or the elements, the earliest written record we have been able to find of the root name of Youngblood is recorded in the 1400's.

In 1474 Andres [Andrew] Jungebloedt had a son to be christened Jakob [Jacob], the record being in a church record personal book of one Geistlicker, who kept only the names of Amtlich (official) men of the church in it. Andres is guessed to have been an official of the church at that time.

During the year 1516 the brothers Lutze (von Lubert) and Lutzo (von Heiden) divided their father's estate. The oldest resided in Fort Hagenbeck and the youngest moved into the house in Engelrading in the county of Heiden. The younger brother was married to Catherina von Westerhold of the House of Lembeck. Among many children, two sons were named Wennemar and Bernhard. About 1583-84 the oldest son, Wennemar, inherited his father's whole estate, but in the year 1602, because he wanted to marry a common girl, Sophia Schweders, daughter of Major Arnold Schweders, he had to let his brother, Bernhard, take over the entire estate (for reasonable compensation). Bernhard was married to the daughter of the Count of Mark, Cunera of Neuhof, who was equal in rank to Bernhard and Wennemar. When Bernhard died, Wennemar tried to get rid of the widow and her children, who were residing in the house of Engelrading. A lengthy lawsuit followed that finally reached the Supreme Court in Speyer. The widow and her daughters moved in with her son-in-law, Deitrich Ophaven, the only son of Arnold von Heiden. Around 1618, Wennemar died leaving three sons.

The new owners of the estate reached an agreeable settlement with Arnold of Heiden. They gave him use of the house in Engelrading for the remainder of his life. Only the first name of his wife, Catherina, is known and it marks her as likely to be of common birth (not of noble family). However, the connection to the house of the Count of Velen must have been excellent, as the oldest daughter, Catherina Margaretha of Heiden, was married to Adam Kock of the House of Velen.

After Wennemar's death, his wife, Sophia Elizabeth of Heiden, remarried with Vogt Bernhard Albert Holleschlott. Sophia had given birth to three Jungblodt sons and had six children by Holleschlott. It is known that her youngest Holleschlott son was ordained around 1707 at Muenster.
