sorry,this is an old thread, but since I last posted I found two records of baptisms, one in 1822 for Jane/William Corkill for Robert arthur, it says received 12 November 1829 on that record. Then another one for Rebecca/William corkill for Robert , it also says received 12 november 1829. William died in June 1829 as far as I know. the one for Rebecca/William says Robert was born 20 january 1822. no birthdate on the one for Jane/William.
