Andrew Ellicott (1733 - 1809)

:"For other people with the surname Ellicott, see there."

Andrew Ellicott (1733 – 1809) was one of three Quaker brothers from Bucks County, Pennsylvania who chose the picturesque wilderness up river from Elk Ridge Landing (known today as Elkridge, Maryland) to establish a flour mill. John, Andrew, and Joseph Ellicott founded Ellicott's Mills which became one of the largest milling and manufacturing towns in the East.

The Ellicott brothers helped revolutionize farming in the area by persuading farmers to plant wheat instead of tobacco and also by introducing fertilizer to revitalize depleted soil. Charles Carroll, a signer of the Declaration of Independence, was an early influential convert from tobacco to wheat.

Andrew Ellicott was the uncle of the famous surveyors Andrew Ellicott and Joseph Ellicott.
