There are now WikiTree surname index pages - for instance, the Seaver Genealogy page.
The Quick links for members include:
* Table view
* Alpha order
* Date order
* Error report
* Find matches
* Follow activity
* Include current last name
* Limit to watchlist
* Merging and matching
* Pending merges
* Recent Activity
At the top right of the page is a list of related surnames with the number for each on WikiTree. There are 579 SEAVER entries on WikiTree. On the right side of the screen is a search box, and below that are photographs from the profiles, and below the photos are links to records for marriage records, death records, census records, and newspaper records from the MyHeritage record collections.
Most of the page consists of the list of persons with the surname on WikiTree. Living people cannot be accessed, but those not living can be. The list seems to be in the order of "last edited" with the most recently accessed at the top of the list.
For a one-name study researcher, this Surname list would be an excellent tool to find additional persons for the one-name study.
A search on a list like this might turn up duplicate profiles, which could then be merged to remove the duplicate profile.
If you have profiles that you manage on WikiTree, you should take a look at these Surname Index pages. I think they're great.
WikiTree is free to use, and to add data to the interconnected family tree. This is an OUR tree, not a MY tree system. Duplicate profiles can be merged. A GEDCOM upload can be used, but the profiles are double checked with possible existing profiles before they are added to the WikiTree.
I have added over 6,000 profiles, but they all need to be edited. I note that there is a link in the WikiTree news item for a Gallery of Examples on what a good WikiTree profile looks like.
