Question

Birth and Death year, she was 5 when died?

Answer 1

Good catch!  I am not the profile manager, but this is definitely something that should be addressed, as Constance would have clearly had to have lived past the age of 5 to marry and have a large family.

Answer 2

Take a look at the Henry Mangum's (Mangum-151) biography.  it references a will that she witnessed October 3rd 1754.  Her last child was born in March 1768.  She would have died after that date
