Frederick was a farmer and the agricultural census data from 1850 shows him owning 15 improved acres and 35 unimproved acres. That year he produced 23 pounds of wool, 3 bushels of peas & beans, 220 bushels of potatoes, 220 pounds of butter and 12 tons of hay.
Frederick and his brother George had jointly inherited a property called the "Patten Farm", but he apparently lived in the Ruggles House with his mother and sister Lucy. After Ruth Ruggles' death, in 1859, Lucy and Frederick shared ownership of the house. Each owned half of the house and had joint ownership of the front door and staircase. Eventually Frederick acquired the whole house.
In 1847 Frederick married Caroline Stone Bucknam, a local girl 12 years his junior. They had two daughters, Emily, born in 1850 and Lizzie born in 1852.
He died in 1890 at the age of 89.
