The present-day and 30th-century family trees of the Wests and Allens are for the most part well-known. Over the next thousand years, we know of a few Allen descendents and a few Thawnes. There are others, both Flashes and Cobalt Blues, whose centuries or lineage are unknown, and who cannot be placed here.
Yes, the 30th-century tree is partially duplicated from the 20th-century tree. However, it shows Iris’s real parents (she was sent back in time and adopted by the Wests) and makes it clearer how the 20th-century Allens and the 30th-century Thawnes came together after Barry and Iris settled inthe future. It is unknown what happened to the Allen line between the 28th and 30th centuries.
Two major issues with the 2007 relaunch of The Flash. First, with Bart Allen’s death, there is no one to carry the Allen line from the 21st Century into the 23rd. Second, with the naming of Iris and Jai West, they have replaced the Kingdom Come Iris West II and Barry West.
