The only advice I can offer is that which I followed myself: Will the information harm or offend any living person on any reasonable level?
My GGGrandfather was a suicide. The people who had to live with this fact during their lifetimes as wife, child, in-law or grandchild are all gone. I can think of no reasonable claim to being offended that any of my co-decendants might have, so I posted the facts.
Such is (was) life?
As for legalities - facts are facts and suicides are public information.
But it is good to show such concern rather than just plowing carelessly forward.
