I used the link shown in your recent thread and looked at this one.
You made no comment after toastbutler's post on 11/9/2012 - did you follow up on this?
First of all, as with most of the other suggestions for the middle name of James, I agree that the name is Kingswell and it really seems too much of a coincidence for an Ellen Collins and 4 children which included a Charles Collins who was born, as detailed, in 1904 whose age matches exactly with the Charles you seek, to have a Kingswell living with them! Other searches show that this man was a Stoker in the Royal Navy.
You really need to look at the 1911 census referred to - we are not allowed to post details of this particular census - as I think it is crucial to your research.
I also think you need to get the birth certificate of Charles (or one his siblings who had 2 Christian names) to a) determine whether fathers' name is James Collins and b) establish who precisely Ellen was in an effort to find a marriage.
By 1911 Ellen could have been separated from her husband and 'Kingswell' (who just happened to have the same occupation as your Charles' given father) may have been more than a boarder!! Charles may well have incorporated Kingswell into his fathers name if Kingswell had become a father figure. Who can say at this stage.
In 1901 at Royal Navy, Hampshire there was a James Collins 31 Stoker b. Scotland, shown as married, on Duke of Wellington - could this maybe be James? (ref.RG13 - 1000 - 44 - 4).
I cannot see a likely marriage for an Ellen born in timeframe/place of later census and it's equally possible they may not have been legally married although lived as such. It is, therefore, important to establish Ellen's maiden name to ascertain where she was in 1901 - not found under the surname Collins anyway.
If Ellen's husband/Charles' father was indeed a James he may well have abandoned his family, a trait that Charles seems to have inherited.
I really do think you need to pursue this family if you haven't already done so.
