Hi I was asking my google home System. Questions the other day about Ancient Rome it knew most of them: but when I asked google home Who is Mark Anthony it tells me he is an actor and a singer. I ask again and tells me he is professional wrestler.
It may not be able to tell the difference in your voice between Marc Anthony and Mark Antony. Think of the latter, the Roman one, as Marc Antoni. You can also say, "who is General Mark Antony?"
