Following the completion of the stockade walls, Todd was elected one of four Gentlemen Trustees with David Mitchell, Henry McDonald and Michael Warnock following a town meeting held on March 29, 1776.
[5] Todd and his two brothers fought in the western theater of the American Revolutionary War under General George Rogers Clark during the Illinois campaign and, as a lieutenant, was present at the capture of Kaskaskia in 1778.
[6] Following the campaign, Todd and his brothers returned to the settlement to encourage other pioneers to settle in Lexington as well as defend against occasional Indian attacks.
[9] That same year, he founded Todd's Station on the northern bank of South Elkhorn Creek on the road the mouth of the Dick's River.
For twenty-seven years until his death in 1807, he was chiefly responsible for recording depositions, the relinquishment of dowers, furnishing and keeping records of road surveys, making lists of taxable property, issuing marriage licenses, drawing up and keeping deeds and mortgages among other administrative duties.
[10] He also served as a major in the Fayette County Militia and, on August 16, 1782, he led 40 militiamen from Lexington and Boone's Station after receiving news that British Captain William Caldwell and an Indian war party were raiding Bryan's Station, a small fortification five miles (8 km) north of Lexington.
Located on Richmond Pike outside Lexington, the house was named after the small Scottish village Ellerslie where the Todd family originated during the 16th century.
The estate had a number of outbuildings, particularly a stone round house where Todd stored the public documents of Fayette County.
Among his possessions included silver, fine china and leather-bound books; his personal library also contained rare works by Mary Wollstonecraft, Edmund Burke and William Blackstone.
[9] The family home was inherited by Robert S. Todd, who in turn left it to Margaret Preston in 1857, before its purchase by the Lexington Water Company in 1884.
