1877 August. Night of 18th or Morning of 19th. On the Sands of Uig near Ardroil Farm in the Parish of Uig.
[Cause of Death] Drowning. Dr. Alexander MacLean, Garynahine, saw body after death.
The informant was: John MacAulay, His X Mark, Employer, 56 Surrey St., Glasgow. [And the informant's "signature" [i.e., the "X"] was witnessed by the Registrar, James Macrae. If the informant (or bride or groom) could not write his/her name, the Registrar would write the name and add His Mark, leaving enough space between the two words for the informant to make a cross, and that would serve as a legal signature for the purpose. The Registrar would have to watch as the person "signed", so that the Registrar could describe himself as a witness to the signing]. The spelling of names and places was always the Registrar's spelling ... and not all registrars were competent spellers!
As I said in my original reply to this, burials were not recorded at that time anywhere in Lewis and the incident would hardly merit a mention in the mainland newspapers unless the other family members thought to place a death notice in the paper - and that is unlikely, I would surmise.
If he was the only member of his family in Lewis at that time, he would simply have been buried in the cemetery (plot of land) used by the people in that area at that time and the location in that cemetery would be unmarked (but it would be obvious that there was a body in that spot). Do you really think that family would have been able to afford preparation of the body and transport of the body to the mainland? That would have incurred quite some expense.
