Perths two eldestfemale Rothschilds, Misha and Marama came from Orana, where they were born. There father was a male called Jaffa. Armani also came from Orana and his grandmother was (is?) a sister to the Perth two. Armanis father(Harold) is also the father of his mother. So unfortunately there is a fair bit of inbreeding going on here. This is to be expected when we cannot bring in anymore giraffes.
As for Marama. Her calf was Jandamarra (this giraffe, I think, had leg problems - not sure though). He was sent to Weribee as an adult where he later died. Marama also had at least one other calf that didn't live very long.
