From looking at his pension file at Ancestry, it indicates that he married Katherine Barrett in Gursey on 23 Jul 1910 and they had one daughter named Beatrice Doris who was born 5 Feb 1918 in Southampton (Free BMD lists a birth for Beatrice D. Marshall in Southampton in the first quarter of 1918, vol 2C, page 110). The file doesn't say anything about a death but I did see a death for a Beatrice Marshall in Southampton in the 2nd quarter of 1918 who was under a year old (vol 2C, page 62). I have no idea whether this is the same Beatrice.
As well, his next of kin in the pension file was listed as his uncle J. Porter, not "T".
The only marriage I could find for a William Marshall and Elizabeth Breaker occurred in Brigus, Newfoundland on 2 Nov 1911 which doesn't work with the information from the military file.
