I hesitate to put this up as it looks likely to be a giant red herring with only the most tenuous possiblity and I can find no way of taking it any further anyway.
On Free BMD the only male I can find born in Wales, with any kind of names which have anything to do with your chap and at the appropriate time is:
Dec qr 1855
David HOWES, reg Merthyr Tydfil, Vol 11a, page 285
Looking for this family on the census I can only see them in 1861 at 24 Lamb Lane, Merthyr Tydfil
Mary Ann Howes 34 Mar? Flannel dealer b Newport (there is a mark across the Mar column so
may be Unm)
William Howes 8 b Carmarthen
David Howes 6 b Merthyr
Mary Watkins 14 servant b Dowlais
Looking as far as 1885 on FreeBMD I cannot find deaths for any of them in S Wales nor a remarriage for the mother - nor even a marriage in the first place. Obviously there are many reasons which mean that they are not able to be found in later censuses. The only other HOWES I could see a mention of on FreeBMD is the death in 1860 of a John Harvey HOWES reg Swansea.
I told you it was very unlikely but I wondered if this Welsh chap emigrated and then was adopted by HNE and took the Henry and EDSALL names, keeping his own as well?
