Can I help you tracing back? You are probably related through Daniel Putman from Illinois who went to Oregon in 1946. Let me know where some part of your Putman family was in 1930 or 1940 and I should be able to help.
Here is one family in the 1940 OR census that was in Cottage Grove
CHARLES PUTMAN Row River, Lane County
He is 45 ID, his wife Abbie M. Scouton is 39 MN and they have Clyde Arthur 11 OR, Betty Jean 9 OR and Edna Irene 7 OR. Charles Simeon Putman is a son of Thurston Lane Putman and Olive Wycoff. His folks were from Oregon. Thurston was a son of David Hazeal Putman from Linn County Oregon. Thurston moved to Idaho County Idaho and was there, as was Charles, in 1900. They returned to Oregon where Thurston died in 1913. In 1920 he was in Yakima County Washington and was married to Olive May Pitcher from Oregon. They were married in Nez Perce County Idaho February 4, 1917. He married Abbie here in Lane County December 16, 1927 and they were here in Lane County in 1930 and 1935. He is a farmer. His mom has remarried and is here in the County now too. Charles was born November 28, 1894. Abbie was born in Hewitt, Minnesota October 22, 1900 and will die in Cottage Grove, Lane County on March 24, 1977. Charles died November 26, 1974 just 2 days before his 80th birthday. Southern Putman family.
But all the folks in Lane County were connected to that Putman line from Illinois and South Carolina before that.
