Oil Painting Artist Identification (Take 2, hopefully they are sized right this time)

Hello, second try at this. Last time the pictures weren't sized right. If I screw it up again, please let me know and I will try to fix it.

Over the past 10-20 years I purchased a bunch of oil paintings and they have been hanging on my wall ever since. I know the one signature is easy to make out but I have no clue who the artist is since there appears to be tons of artists with the same name. I would like to identify who the artists are (I like to learn as much as I can about the paintings that I have), and the second reason is I would like to add them to my insurance policy if any have any value.
