Thank you WikiTree!
I got an email from someone on WikiTree asking for information about OUR great-grandmother, Mary Maud Briley who was born 1877 in Kansas her father is John G "Gus" Briley and mother Elenor Greenwell. Mary Maud married John Spivy Armstrong and they raised their family near present-day Wann, Oklahoma when it was still Indian Territory.
What a wonderful way to meet an awesome cousin! She only lives 20 minutes away! I have a new known family member and lunch buddy!
