I seem to recall that there may actually be a book out on the subject; a search of web sites for major book sellers may bring it up. Yet, finding out why a particular snake or two was so named may not be as hard as you seem to make out. I did a single web search on 'Children's Python named' and one of the top listings was a link to a site that explained for whom this snake had been named.
As for the Children's Python, it was named after John G. Children; see these references:
Burke's Backyard - Children's Python and
Short Bio John George Children.
When you find out the reason a Carpet Python was so named, let me know ; one good deed deserves likewise.
Happy New year,
