Hi Jim, Looks possible that he arrived WALKER James 19 years old on the ship Rippingham Grange on 13 Apr 1911 It looks as though the family came out to Australia.. minus Dad.. there was a family of 7 Walkers on the same ship on the same date... So big chance they are siblings and Mother.. by the looks of things. I know you said that you didnt want the shipping details however it looks promising that your 1911 guess is right... you can see these details yourself on the Queensland State archives online indexes, at the following http://www.archives.qld.gov.au/ Anyway hope this helps Sue.
