I only looked at a couple, until I found one old enough to get past 'Personal recollection.'
Your citations do make it possible to find the sources, which is important. I think you should expand the source citations, and add links if possible. FamilySearch makes it super easy. For example:
"Illinois, County Marriages, 1810-1940," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:QK9L-W7TT : 14 October 2017), William Isaac Sprout and Evelyn Katherine Hull, 14 Feb 1918; citing Warren, Illinois, United States, county offices, Illinois; FHL microfilm 1,255,935.
You can just copy/paste that into Evelyn's profile.
Also, for list-type biographies (like Evelyn's), it's a good idea to sort the sources chronologically. Then they provide a timeline.
Finally, even for people you knew, like grandparents, you should try to add sources as if they were strangers. Never know what you might find!
Good job for a newbie!
