How Many Names in One Name Study?

+7 votes
117 views

When I display the page for the Category: Chadwick Name Study it shows what it says are 200 names in alphabetical order (I haven't counted them) starting with Aaron Chadwick and ending with Ethel May Chadwick. When I ask for the Next 200 it shows 67 names, but they start with Abigail Chadwick and go through to Zebediah Chadwick. OK. I am not sure why there is this overlap, but I take this to mean that there are 267 names that have been categorized in the Chadwick One Name Study. But then I click Previous 200, expecting to get the first list back. Instead I get a list that includes people that were on neither of the first two lists, like Zipproah Chadwick. What is going on? After two clicks of Previous 200 I get a list that starts in the same place as the first list, but has only 57 names. How do I determine how many names are actually in this category?

There's clearly some error in the way the names are displayed, but I'm not authorized to see the underlying code to tell what's wrong.  You might want to post it to the tech section so that people who don't read general questions will see it.

All people-categories (except Unsourced Profiles) tend to lose people where an LNAB crosses a page break.  The more members there are that have the same LNAB, the bigger the problem.

It seems to happen because the paging system thinks the list is sorted in order of WikiTree-ID.

Possibilities

1 - One thing that seems like it ought to work, but who knows, would be to apply the category to each profile using

[[Category:Chadwick_Name_Study|{{#profile:LastNameAtBirth}}, {{#profile:RealName}}]]

Ideally this needs a template.

2 - Another way is to break up the list into smaller categories, less than 200 people.  There's an official scheme for doing it by place - the format would be [[Category:Franklin County, Pennsylvania, Chadwick Name Study]].  Or they could be split by first name "Chadwick, A" "Chadwick, B" etc.  Or by immigrant, if you can separate them into tribes.  Or whatever.

3 - The Unsourced Profiles category works round it by being sorted by ID instead of name.  This jumbles the first names but makes the paging work.
