Thinking about it, Ford has interacted (directly or indirectly) with all the above: Delores (in various timelines), Maeve (well, through Clementine being "disabled"), and obviously had drinks with MiB. His interaction with William has only been through Delores.
The only point of mentioning that is Ford is obviously the same age with TL2 and TL3 above, but since Delores is "one of the originals", we don't know at what point her interactions have occurred with regards to Ford and William.
Also, not sure how I missed this one. Look at William's shirt and MiB's shirt.
