Just here what Lilly says:
"If a question be demanded of one absent in a generally way, and if the q u e r e n t has no relation to the party, then the first house, the Lord of that house and the Moon shall signifie the absent party; the Lord of the eight House or Planet posited either in the House or within five degrees of the Cusp of the 8th House shall shew his death or its quality. ....."
So, the Lord of the ASC is Mars posited in the 3rd and opposites Venus, Lord of the 7th and 11th. Mercury (Lord of the 8th) is the most near the cusp of the 8th, but I cannot see, at how many degrees he is distant from this cusp.
All in all, there are three planets in the 8th, Venus, the Moon (the true mother?) and Mercury. As the Moon is in opposition to Pluton (even that Pluton isn't considered by the ancient astrology), I think, that she is separated from the death, or she has been excluded from inheritance and richness or something of this way.
IMO, the only thing Neptunian has to do, is to continue her search.
