JPRG67 on Family Tree Circles

I am Looking for any information on Joseph Peters born 1842 died 1900 in Melbourne, i believe he resided in Dromana/Rosebud in Victoria Australia and was from Baltimore USA he was married to A Mary Ann White and had 15 Children one of whom was my Great Grandmother (Ellen Phoebe Peters) any information would be apprciated as we have questions about our ancestry as my Grandfather Les Peters is the son of Ellen Peters ( Father Unknown) and was made a state ward and was fairly Dark Skinned and was designated Aboriginal by the AIF in World War 1.
Les was a decorated war veteran and worked in Mental health at Mont Park Mental Hospital for over 40 years and was a well respected and loved member of the Northcote Community in Melbourne and was the secetary of the Limbless Soldiers Association for 25 years he was born in 1899 and died in 1994, and we believe he had 2 brothers (Joseph Claude Peters) and (Eric James Peters) which he never knew and he also was brought up with his Cousin Olive May Lovelace nee Peters born to Maud Peters ( Ellen's Sister) in 1900 and died in 1997 in Frankston.
so far I have found that Joseph Peters was a Fisherman and possibly jumped ship in Dromana and was possible from The Cape Verde Islands , this would solve a lot of questions as a lot of my family are of darker skin complexion and with black curly hair.
We have been informed also that my Grandfathers Father (Philip Mulhall) was of aboriginal decent.
Les was married to Myrtle May Logan in 1922 and had 3 children Norman (Dec) Mavis ( Dec) and Ken (Living, My Father) all of whom never knew there Grandmother or other relatives as both parents were wards of the state.
