I'm not quite sure if Guy Spencer and Thirza Austey/Hall are Alice Spencer's true parents (ancestry.com records state them as her parents). Alice is likely adopted to them.
For example, Guy Spencer was born circa. 1837-1838, whereas Alice was born on 1896 in Doynton, Chipping Sodbury, Gloucestershire, England. That's a 58 year difference!
How is it possible for a man to father a child biologically at age 58?
