Here's my timeline (keep in mind that the ANH screenplay describes Luke as 18 years old):

- 35 BBY or earlier: Clone Wars begin

- 35 BBY: Battle of Honoghr

- 30 BBY: Nejaa Halcyon dies

- 20-25 BBY: Bpfasshi incident

- 18 BBY: birth of the Empire, extermination of the Jedi, and birth of Leia and Luke

Now that I think about it, you can have the Clone Wars end as early as 25 or 26 BBY. That way, the long period between its start and end can fit all of the events, including the Bpfasshi incident. With Nejaa Halcyon, he still dies then with his kid about 10 or 11 years old. By the time the Empire's rises (19 BBY), Halcyon's kid is 17. You can say Halcyon's kid married young (say 18 or 19) and had Corran Horn almost a year later (probably close to 17 or 16 BBY).
