I know your post is about 2 years old. However, I am also researching the Monday family line. My 2nd Great Grandfather is John Vincent Monday (b 25 Sep 1856 and d 27 Jan 1938), who is the father of William and Ellison, and many others.
Here's briefly what I have...
Elison (or Ellison) Bedford Monday (1876-1943) married to Della Geralds with 16 children.
John Vincent Monday (1856-1938) married to Hettie Francis Steele (1860-1933) with 15 children.
Elison (or Elizor or Ellison) Monday (born abt 1817/1820) married to Evaline Gearlds with 3 children.
And, this is where I am stuck.
Of course, the Monday name was also spelled Munday, Mundy, and Mondy. Although the majority of people were born and died in Tompkinsville, Monroe County, KY, it seems that Elison (the older) was born in Virginia.
I would appreciate any help anyone can give me. I do have further details on the people listed above and their descendants, please feel free to contact me if you are interested.
