Here is what I have regarding Margaret DAWLEY. She married Lawrence BREEN of Petty Harbour, NFLD. on May 2, 1879.
Then this family shows on the 1891 census for Montreal showing a birth date for Margaret as 1856. (I'm not sure this is correct)Children for this couple born in Quebec: Margaret b. 1882, Lawrence b. 1887 and Mary b. 1889. This family was in Montreal as late as 1896 as they were witnessed a marriage there. After that they leave to go _?_.
I wrote NFLD Archives for a copy of the Baptismal cert for Margaret. I don't know how long it takes. And with my kind of luck, it will say "parents unknown".
I viewed every DAWLEY on this forum and also contacted Richard Eugene Jonsson but he has not responded as of yet.
The Boston, MA Directory for 1890 is on Ancestry.com. They also show Albert H. DAWLEY, collector, location 190 North Beacon; Harry N. DAWLEY, agent, location 521 Washington, Room 11, at Somerville; and William J. DAWLEY, teamster,location 2061 Washington and location at 3 Bartlett Court.
It is interesting to have a John DAWLEY with a wife Catherine and also BREEN families in the Somerville, MA area.
