The following bio of Richard Sedgwick appears in History of Waukesha County
by Western Historical Company, Chicago 1880:

RICHARD SEDGWICK, farmer, Sec. 12; P. O. Merton; was born in Yorkshire, England, in 1840; in about, 1849 he came to this country with his father, Richard Sedgwick, his mother having died in England; they settled in the town of Lisbon, Waukesha Co., Wis., where he married, in 1870, Laura Weeks, she was born in Lisbon in 1847, and was the daughter of William Weeks, a pioneer settler and esteemed citizen of that turn; they have one child, Alice May. He owns a desirably located farm a short distance from the village of Merton, and in the vicinity of Lake Keesus, a beautiful sheet of water covering several acres and abounding with fish; his father is now a resident of the village of Pewaukee.

Richard said in the 1900 census that he had immigrated in 1853, but he as was here for the 1850 census, the above statement "about 1849" as the imigration year is probably correct

Children:

Alice M Sedgwick
