Hi Robin,
No, I have no idea who the Robert and Mary Ann aboard the Trusty were.
Robert Allen Wade was a completely different person -- he was the grandson of William Wade & Mary Peacock. He was born in South Australia in 1869, the son of their son William. He married (1) Hulde Magdalene Schirmer, and after her death (2) Ethel May (“Maisie”) Smith. Uncle Bert was a child of the second marriage.
Cheers,
Jestina
