Many if not all stars form with others in a stellar nursery, often from the
shock of a nearby supernova, if my readiing is correct.
So, why are we so reltively alone? Where did our suiblings go? And where is
the remnant of our long-lost mother?
I expect 4.5 billion years of stellar drift and galactic orbital mechanics
have scrambled things pretty badly, but is there no trace of the Sun's
relatives to be found?.

Not yet, for exactly the reasons you gave: most "open" star clusters
break up in tens of millions of years. 4.5 billion years later, you'd
have to do a lot of hunting to find Sol's siblings.

See the intro paragraphs here:

I also recommend this month's copy of Scientific American for an article on
exactly this topic.
