"Panamal Canal", lol. They (ancestry) also have American Samoa and the Virgin Islands, as well as Delaware, DC, Indiana, Maine, Nevada, and Rhode Island so far. I don't know if any of these are complete. Some have more counties available than others do.
The new US findmypast site has a facility where you can tell them who you want to find and they will let you know when those records are available:
