That Family List you describe is a list available under the tab that is labeled with your ID. Yours is at https://www.wikitree.com/index.php?title=Special:FamilyList&p=11462546
The 42 people on that list include you and 41 other people who are connected in WikiTree as your direct ancestors within 10 generations. It does not include the aunts, uncles, cousins, and spouses who many of consider to be part of our family trees. However, at the top of the screen there's an option to add siblings of your ancestors to the list; when I did that for your list I got 105 people. And if you are looking for ancestors previous to the last 10 generations, you can increase the number of generations on the list.
If there are people on the list that you don't recognize as ancestors, it's possibly that another WikiTreer connected them as parents to one of your known ancestors. (Maybe a distant cousin found some additional ancestors for you!) If the list is missing some of your direct ancestors, it's possible that someone changed the parents on one of your ancestors.
If changing the options on your list doesn't resolve your concerns, I suggest that you explore the names on the list -- and look at the change histories on the profiles to see if they've had new families members added, or old family members deleted. Hopefully you'll find that other members have improved your tree, but mistakes happen sometimes...
