Newspapers in the period 1899-1901 mention several times P/M P. MacDonald of the 4th Volunteer Bn Black Watch.
But there was also a P/M Peter MacDonald in the 3/6th Bn Black Watch during WW1.
The 4th Vn. Bn became the 6th Bn in 1908.
Does anyone know if they are the same person or have more information about this/these P/M(s)?
