My apologies, I typed that without looking it up. He was a half brother to the Greenwoods and a cousin to the Warrens.
Winnifred Warren was married first to Joseph Jeffries Sr., they had one son, Joseph Jr.
She was married second to Daniel Greenwood. Daniel and Winnifred were the parents of Bill and Ed Greenwood.

JOSEPH JEFFRIES, Jr. was born Abt. 1833 in Kentucky. He married ANN M..

In 1850 Lafayette Co MO census where Joseph Greenwood is listed as oldest son in the Daniel Greenwood family. That is probably Joseph Jeffries, son of Winifred and her first husband, John Jeffries.
In 1860, he, along with his family, is listed with Daniel Greenwood's household as Joseph Jeffries, in Johnson Co.
