My mcwatters family also traveled between Ireland>u.s>crossed border to Canada>back to Glasgow.
Lists parents as William and ? as Irish and children Ruby and William as British Colony.
I have 4 ships so far accounting for voyages dating approx. 1903->1920 returning to Ireland.
Sailing in 1911 mentions wife 35, ROSE 10, RUBY 8 (bn. 1903), WILLIAM 4, The last few names are very difficult to read...I think are MYRTLE 5, MILDRED 3, H*RB*RT 1.
This is my first search for this side of my family. Im sure if anyone finds this useful I could find out more . This is family of my stepfather William James Wallace bn. 1933 Northern Ire. who is son of RUBY MCWATTERS.
