I think he was a very good looking young man. It's an interesting picture as I see the same expression on my oldest son.
M M (as he was called) was born in Collin, Texas on March 17, 1868. He was the oldest son of George O. Yeakley and Lydia Grubbs. He was 18-yrs-old when my grandfather (the youngest child) was born.
In 1887, he married Millie Elvina Robison. He was 19, she only 15. However, it was a marriage made to last as they celebrated their 50th anniversary on December 4, 1937.
In 1904, M M was the postmaster for Mountain View in Cooke County, Texas. In the Fort Worth Star-Telegram, there was a blub about Mr. Yeakley. It reads, "M M Yeakley, postmaster at Mountain View Cooke County, who is under a charge of violating the postal laws, had a hearing before the commissioner at Sherman and has been released on $500 bond." Unfortunately, I don't find any other remarks concerning this case so don't know the whole story or the outcome. However, the Quaker genes must have kicked-in because the rest of his life seems to be ideal. He does look sort of angelic in the photo below.
M M died in Gainesville, Texas on April 14, 1946 at the age of 78. Millie followed him two years later on July 9, 1948. Her obituary says she was well respected for her exemplary citizenship. She must have had a very good effect on her husband.
