These are likely generally known names, but a few friends and family have used both of these guys for wrongful death and inheritance stuff.

Morgan and Morgan is definitely good.

Ludovino Gardini is good, but I don’t have personal experience.

On the Western Mass side, I would use my lawyer above all these guys, Dan Kelly, but I understand wanting to keep it local. Another friend also said Michael Levin (Sturbridge, I believe)

These guys appear to be Creme de le crop for Boston and mediation law, but neither myself or my ‘colleagues’ have used them.

I could write a book about cases they’ve won close to me, but that’s anecdotal evidence at its best. I suggest reading up on case outcomes on these guys and stuff to make the best decision for yourself. From what my practicing family is telling me, inheritance/mediation law is usually tricky and you’ll need someone decent if you’ve been pushed out by a husband/wife of the deceased.

Edit; I just noticed you said uncle but the sentiment is the same.
