First, I learned the site doesn’t work well in Firefox, so I switched to Safari.
Community Trees has lineage-linked genealogies from specific places and time periods (some date to medieval times) around the worldfor example, Millville, New Brunswick, Canada, and Norfolk, England, in 1563.
Here’s a description of current trees. They include communities in Britain, Scotland, Wales, Iceland, Norway, Pacific Islands (including New Zealand), Canada, and Washington State.
Each tree is a searchable database with views of individuals, families, ancestors and descendants. Most are joint projects between FamilySearchs Family Reconstitution team and local residents or genealogists with expertise in the area or the records used for each database.
Search across all data by name from the home page. Once you click on a name, tabs show you the person’s ancestors and descendants, let you calculate his relationship to another person in the tree, display a timeline, and let you download a GEDCOM (in some cases), or suggest new information.
Links at the bottom of the home page let you search for dates, places, cemeteries, histories, etc. Not all seem to be fully working, but you can click the Sources link to search the source citations used for the information in the trees. Each source is linked to related individuals.
Since the site is being tested, you can expect that some features wont work all the time. Give feedback using the Contact Us link, which is under the Info tab at the top right of most pages.
