And by WA1 we mean a haplotype identical to WA1 that was in Wuhan before the 15th January

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

Total sense and I fully agree. I suspect the emergence event took place elsewhere and was imported into Wuhan.

Can you just summarise where the root should fall? I didn't follow all that chain.

Curious though that the Malaysian one is one SNP closer to RmYN02 than all the others. So possibly that one (but the January cases in Malaysia were Chinese nationals visiting)

So I think most parsimonious would be `Malaysia/MKAK-CL-2020-6430|EPI_ISL_416886|2020-02-04` -> `WA1` -> `WH04` -> `Wuhan-Hu-1`

Would it be worth trying to simulate a WA1 with a date in the beginning of December and run beast?
