The MB in 199:6:(12) <page 204, Vol 2> says: "... even a woman with
her husband and sons, it's also incorrect to have her join [to
complete the threesome]..."

The Shaarie Teshuva (ibid) actually brings the Gan HaMelech (Siman 75)
who mentions that a certain Gadol used to make a Zimun with himself,
his daughter and her husband, and the Gan HaMelech disapproves.

Reading between the lines, it seems like technically it should/could
be permitted, but the Minhag was to not do so.

So this is an "ancient" discussion. :-)
