The McManus family has such a deep attachment to WA that not many leave the State, so learning his family tree branched to South Australia was something of a surprise for Perth-raised, Los Angeles-based TV presenter and comedian Rove McManus.
"All my family is in WA as far as I know," he said by phone from LA.
"For any generation I can see, no matter how wide we get, there's a lot of us. I am one of the very rare few who have moved interstate and now overseas. There are still a lot of us swarming around."
McManus learnt during filming his episode of the popular SBS genealogy series Who Do You Think You Are? he is related to Mary and Robert Thomas, one of the founding families of South Australia.
Mary was an acclaimed poet and diarist and Robert, the government printer, printed the South Australian proclamation document then went on to publish the South Australian Gazette and Colonial Register.
McManus said the historians and experts weren't told who was coming to see them, only that this person didn't know he was related to the Thomases.
"One of the historians apparently responded 'Who would be related to the Thomases and not know?'"
"If you live in SA they are a big deal, but I was completely unaware."
McManus was back in Perth to see his family at Christmas and New Year and stayed on through January and February to hit the road for WDYTYA, travelling to Halls Creek to learn more about his great-grandfather, acting warder Charles James McManus.
"It was so hot up there, it was stupidly hot. I'm out in the sun, I'm roasting, but at the end of the day I can go back to a hotel and air-conditioning or get into a car, or have a cold shower, or if want, have another one within 10 minutes. But for my great-grandfather who was living and working there at the time that would not have been the case, there was no such thing."
Also explored was a crime allegedly committed by Charles.
"No one knew anything about that, he had already passed away when my grandparents got married," said McManus.
"I had no idea what I was headed into; the only clue I got from my grandmother was there was something he had done he said he was innocent of, so I wasn't sure where it was leading.
"Obviously I knew something was coming, he was going to be accused of something he was going to say he was innocent of. It's all part of the process. It was interesting to hear the circumstances of what was going on at the time; it gives you a history lesson."
McManus also learnt more about his beloved pop Bill Bryden, who spent time as a POW in World War II, and had an emotional meeting with one of his former army mates.
"When they say on day one 'We're going to follow your pop Bryden', there was a little part of me going 'But I know him, he didn't die until I was in my 20s'.
"I know him; there's no more stories to tell. Yeah I know, he was taken prisoner and I know what happens, he comes out the other side.
"Then you find that little interesting piece of information and go 'Oh, there was a whole lot of other stuff we didn't know about'. A lot of this was because he never spoke about it.
"Part of it was gee, if he didn't talk about it was this something he didn't want any of us to know? What I did come to realise, having spoken to his battalion mate, is he only just started telling his story and he's in his 90s.
"If my pop was still alive now, maybe he too would be at a place in his life where he was happy to retell these stories and maybe that's what this whole Who Do You Think You Are? experience was, somehow him from the past now telling his story here in the now."Who Do You Think You Are? airs on Tuesday at 7.30pm on SBS One.
