After reading more thoroughly both profiles, it looks like they are saying the same thing, that the father is unknown, with speculation about both men stated in the profiles
It would seem that her maiden name should be Martyn, with the birth source stated in both profiles. Martyn-690 in the Sources has confusing wiki tree ID links stating that 'Richard Thomas' which should be 'Richard Thomas Bowerman'
Maybe the merge could go forward, but I don't see anything compelling to prove who her father was. If her mother had the child before she married Bowerman, birth source doesn't state a father, then no father should be attached. Speculation on the two possible fathers should be included in a 'speculative or conflicting father' section with the Wikitree ID and names and information.
Bowerman could be attached as non-biological, but it all needs to be explained in the biography
