As one of the earliest settlers of the area, Andrew Montgomery established a trading post that later took on his namesake as Montgomery County in December 1837.
"The first settlers began arriving in Montgomery County by at least 1830 or possibly earlier than that," said Larry Foerster, chairman of the Montgomery County Historical Commission. "There was a petition by residents here, at that time east of the Brazos River, to have their own county seat."
In 1837, Montgomery County, located about 45 miles north of downtown Houston, spanned across the present-day counties of Grimes and Walker as well as portions of Madison, Waller and San Jacinto. By the 1870s, the modern boundaries of the county were established to encompass an estimated 1,050 square miles.
The Montgomery County area was part of an original Stephen F. Austin colony included in contracts developed by Spanish and Mexican authorities in the early 1800s, according to the Texas State Historical Association.
