This is a similar query to the one at https://community.logos.com/forums/t/114500.aspx but I thought it best to start a new thread to discuss it.
Danove classifies "who" and "of me" in Mark 3:33 as Patient and Benefactive respectively

But Logos tags "my mother and my brothers" as Experiencer

Any comments on this specific case - and the handling of the complexities of clauses containing εἰμί in general - would be appreciated
Thanks, Graham
