Thank you for that. I think the Charlotte on the 1901 census is correct. Charles was registered with GRO as Arthur Cecil Jun- Sep 1897 born at Hackney. His DOB on his baptism record is 8 Sep 1897, he was baptised at St Matthew, Islington, London on his 1st birthday and christened Charles Arthur Cecil St Leger Wilson. Home address 120 Rotherfield St, Islington, father a Seaman which fits with Arthur Mordaunt Wilson's chequered history which shows he joined the Merchant Navy when he was 17 (1877), deserted his ship 2 years later at Port Adelaide, Australia (1879), it appears he stayed in Australia for a few years and then returned to England. Cecil St Leger wasn't taken to the US by his Aunt Emmeline so he travelled with someone else probably, as you say, by his parents. Emmeline appears to have inherited some money from her grandmother who left the equivalent of £2 million in today's money. I don't know when she 'adopted' Cecil but she treated him as her own son. I'll do some more searching and let you know what I find, if anything.
