Note: this man is often confused with another Isaac H. Brown who lived and died in Milton, Pa. They are not the same man.
RECENT DNA appears to link this man as a child of Absalom B. Brown and wife Mary Jane Green of Warren Co., Tennessee and grandson of Thomas Archibald Brown and wife Cecily Green Brown.

A family legend indicates his name (or his father's name) was originally McDiernee and he came from Scotland as a youth, stowing away on a ship. The name McDiernee (and variant spellings) is associated with Clan Campbell of Breadalbane, primarily of Argyll ; connection remains unverified. Historical research , along with DNA, may suggest the story goes back one generation and refers to the father of Isaac. Note, the line of Thomas Archibald Brown noted above has many of the elements of the family legend.

Although descendants of one line indicate the middle name was "Haire", documentary proof of his middle name is also lacking as the census records show only an "H". His death date is from a family bible of his son, Mithero Berzanes Brown.

Note: there has been some confusion between this man and another man of the same name who lived in Northumberland Co., PA. They are two different individuals but family relationships are being examined and hopefully DNA will further clarify.
Currently, there is no known connection between the "Isaac Hairie Brown" of Northumberland Co., PA and this man. There is also no known evidence of his middle name being "Hairie"; most records found indicate merely a middle initial.

His children all had unique and classical names -

i. PTOLEMA PHILADEPHUS BROWN, b. August 30, 1829, Warren County, Tennessee; d. November 02, 1903, Soldier's Home in St. James, Phelps County, Missouri. "Ptolema" = Greek; Many possible individuals but a probable one is the mathematician author of 'Geographia' (ca. 150).* "Philadelphius" = Latinized form of the Greek word for brotherly love.

ii. JUAN FERNANDEZ BROWN, b. 1831, Davidson County, Tennessee; d. March 07, 1854, Texas County, Missouri. "Juan" – may refer to the explorer Juan de Categena with Magellan.*
"Ferdinand" – may refer to the explorer Ferdinand Magellan. Also, an island chain.* Her child was listed on the 1850 census.

iii. ARCHIMEDES BROWN, b. March 22, 1834, Warran County, Tennessee; d. March 14, 1863, the Civil War in Murfreesboro, Tennessee. "Archimedes" = Ancient Greek mathematician * Hew as reburied in Macoupin Co., Il.

iv. SELTICANA BROWN, b. 1834, Tennessee. "Selticana" = No clear historic, literary references discovered. A form may be found in the term 'Sultana' meaning a wife of a Sultan. It could also be in reference to Celtic origins in the family (Scotland comes from the name of a tribe of people from what is now known as Ireland. These "Celts" lived across Europe sharing a common language, customs, and art. Sometimes the name was spelled and pronounced with a soft "S" rather than the harder Greek "K" (Keltoi). If this was true, the name would mean she who pertains to the "Selt". There is a possibility that this person was the same as a GEORGE S BROWN who appears on the Texas Co., Mo census of 1860. More research is needed to verify gender of this child.

v. LYCURGUS BROWN, b. 1835, Warran County, Tennessee; d. May 22, 1887, Macoupin County, Illinois; m. MARTHA P. ARMOUR5, Abt. 1860, Missouri; b. 1840, Illinois. "Lycurgus" – many possible from ancient history, but possible the lawgiver of Sparta (570-730 B.C.)

vi. MITHERO BERZANES BROWN (seen sometimes as METROBAR JAMES BROWN), b. 1840, Warren County, Tennessee; m. MARY BROWN; b. 1843, Tennessee. "Metro Barjames" - could actually have been Mithro (Persian mythological figure) and "Bar' in Barjames is Hebrew for 'son of' or 'descendent of' – could we have a clue as to the name of one of his grandparents? One source links Mary to a James Mooney.

vii. MARY A. BROWN, b. December 04, 1843; d. April 17, 1887, Texas County, Missouri. Mary's middle name is unknown but thought to have begun with an "A". Her connection to the Brown's is clear in names of one of her children…Arminda, Theodosia, Ozzia, Facelina Mobley.

viii. ELSINORA ODENSIA BROWN, b. February 21, 1845, Tennessee; d. March 1910, Piaza, Illinois; m. (1) KAYLOR; m. (2) THOMAS MCCOY, 1876, Illinois. Twin to Marcellus. "Elsinora" may be reflection of the place in Shakespeare's Hamlet. "Odensia" may be a form of the Scandinavian deity of "Oden" – as a name it has been found in Norway.
