We are from the large family of Matthew and Eliza Havens Chambers, who with many children and relatives migrated to South Dakota to homestead.  When the weather went sour, many of them sold out, went down to Oklahoma for the landrush.  Many lived in Black Dog Township of Osage County, worked in the oil fields.  Others did not move but stayed in Fulton County.  I have a very extensive genealogy involving all of these fine folks and would love to share it.  I have many family pictures also for sharing.
