Oliver Clark Kinney - Dates

I found the source of confusion. There are two profiles for men named Oliver Clark Kinney.

1. This one shows the birth dates of 1827, shows no parents and has the wife Martha Ann Rice:

2. This one shows the 1845 birthdate, lists parents, and doesn't list Martha Ann Rice as a wife:

I'm not familiar with the lines, just tracing them in a tree of a DNA cousin trying to determine how we're related. So I don't know if there was one man named Oliver Clark Kinney and his info has gotten confused or if there were two same-name men born different times and with different wives.

I'm hoping the profile managers can help sort this out.

Thanks in advance for any clarification.
