In 1830 he married Lodemia Ells, who was one year older than he.
In the next few years, five more children expanded their family to nine members.
While William and Lodemia's family grew, he bought 242 acres (0.98 km2), in three separate purchases, thus creating the first section of Cary, Illinois.
In 1845, he built on West Main Street a red brick house, which still stands today.
However, the house was moved to a lot on East Ross Street in 1966, when Ameritech bought the West Main property.
