They're not the same. Everett Ross and Thadius Ross have separate identities and storylines in the comics. Their powers, if any, and character arcs are completely different.
Since I don't have a lot of information about this specific story, it's hard to say exactly who Mike Ross is. He could be an ordinary person with an interesting personal story that involves some sort of growth or change symbolized by 'big boy pants'.
I'm not sure specifically who 'ann b ross' is just from this phrase. It could be an author. Maybe it's someone who has created works within the realm of 'fantastic fiction' which might include elements like magic, otherworldly beings, or extraordinary adventures.
I don't have enough information to fully define who Kara Robinson is just from this 'watch the Kara Robinson story' statement. She could be an ordinary person who has had an extraordinary experience, or perhaps someone who has made an impact in a particular field or community.
The Betsy Ross story is based on historical accounts and tradition. However, historians continue to debate and research certain elements, so we can't be completely certain of its absolute truth.
In the context of a fanfic, Harry and Kara are likely fictional characters created by the fanfic author. They could be based on real - life individuals the author admires, or they could be completely original characters within a particular fan - created universe. Harry might be a charming, kind - hearted guy, and Kara could be a strong - willed woman. Their personalities would be developed by the author to drive the plot forward, especially in relation to the pregnancy storyline.
In the fanfiction, Kara Lemon could be an original character created by the author. She might be a muggle - born witch who discovers her powers later in life and is then thrust into the magical world of Harry Potter.
