I'm not a Briden researcher but this info might help someone.H.T. Briden, son of William Briden, was born in Cook Co., Illinois, in 1837.William and wife were from England.In 1843, William lived in Michigan, then in 1854 moved to Iowa.See the biography for this family at:
http://www.genexchange.org/county.cfm?state=ia&county=bremerhttp://www.genexchange.org/county.cfm?state=ia&county=bremer
When at the site, select Biographies in the index, then search by surname BRIDEN.
I hope this is helpful to someone.
