Max Kennemer was born in May 1900 in Texas.² He was the son of George Washington Kennemer and Hattie Jane Johnson.¹ Max, age 0 years (he's about 1 month old), was enumerated in the household of his parents on the 1900 Federal Census in Justice Precinct 5, Wise County, Texas.¹ Follow the link to see the census image. Max and Roy may be the same person. I have not been able to find Roy on the census and Max was on the census. Perhaps Max was known later in life as Roy.
