The Mounted Rifles Brigades were dismounted and became Infantry battalions on 1 Jan 1916. The 1st CMR, along with the 4th CMR, was manning the 3rd Division's front on June 2, 1916, when the Germans launched their assault at the outset of the Battle of Mount Sorrel. Its positions were overrun, and 557 of its 692 members (80%) were killed, wounded or captured. (Wikipedia)

1901 Census

In the 1901 Census Mark (18) is one of 8 farm servants at Manor Farm, Barrow.
 
On 10th April 1908 he appears among a number of Daltonians (Peter Naylor; James Boundy; Thomas & William Freethy; Joseph William Farren) on a passenger manifest for aliens crossing from Canada to the USA having arrived from Liverpool on the SS Victorian, arriving at Halifax, Nova Scotia on 17 April.  All are listed as miners. Mark’s address is given as 107 Charles St, Dalton. (Looking at the address on the first line, this should be Cleator Street.)
 
There is also a Mark Simpson of the right age, labourer, from Lancashire, arriving in New Brunswick 18 April 1904 from Liverpool aboard the S.S. Lake Manitoba who may be the same person, but the script is indecipherable.
