Who Did Angas Mackcloud Marry and Who Were His Parents

Hi we know that Angas Mackcloud was my GGGrandfather and his Daughter Marion Married An Isaac Eyers.And Their Daughter Ruth Married my Grandfather Joseph Reynolds In Dunedin in New Zealand.We do not know Who Angas Married and who his parents were,and when he and Marion arrived in Australia and from where?
If anyone could help this would fill on a gap in our Family history.

Thanks

Robert
