Rev John Simons of Kent had a daughter Rebecca b 1791 who m Charles Rugg in 1820. The Rugg family owned iron mines in England somewhere.
One of the children of this marriage was another Charles Rugg b London 1831 who m Jane Eaton in London in 1853. They appear in 1861 and 1871 census in London.
May 1873 Charles immigrated to the US with most of the children; Jane seems to have remained in England.
I have found Charles in Clay County in the US 1880 census and again in 1900 and 1910. Some of his children moved on to Montana and California, but others remained in MN, marrying as far as I can tell into the Antrim family.
Surnames in the next generation include Austad, Olsen, Schauer, Berg, McMains.
I'm keen to exchange inforamtion ... does anyone know anything?
[This is to some extent a cross-posting as I've asked similar questions on the Yellowstone, Montana board.]
