William Henry Brandenburg and his wife Anna (maiden name unknown) sailed to America in 1752 aboard the ship "Two Brothers", landing in Philadelphia. They settled in the Frederick, Maryland area.
When they arrived in America, William (born 1722) was 30 years of age.
Family tradition holds that William and Anna Brandenburg were accompanied on the voyage to America by a young relative, Mathias Brandenburg (born 1738). So far, proof that Mathias was with them, and of his relationship to them, has not been found. He could have been William's younger brother, or perhaps a nephew. Matthias was about 14.
Male passengers aged 16 and over were required to take the oath of allegiance to their new country. Here is the list of those who took the oath on 15 September 1752, after arriving on the ship.

Jacob settled in the Frederick County area of Maryland.
Alexander Heinrich Brandenburg and his wife Anna (maiden name unknown) are another Brandenburg family that came to America.
Their date and place of arrival are not as yet known. Two of their children, Barbara Brandenburg (born 1741) and John Conrad Brandenburg (born about 1747) were born in Germany. A third child, Jacob Brandenburg (born after 1761) was born in Frederick County, Maryland.
Our branch of the family is descended from William Henry Brandenburg and his wife Anna, who arrived in 1752.
Their son (also named William Henry) was born 1757/8 in Frederick County, Maryland and married Catherine Bussard. Our family is descended from their marriage.
William and Anna Brandenburg's family expanded from Frederick County, Maryland into Ohio, Indiana and Illinois.
William (the son) served in the Maryland Minute Men during the Revolutionary War, receiving a pension for his service. He is shown in Frederick County in the first US Federal Census (1790).
