Hello Glen: I think I can help you a bit regarding Walter Dalziel & Elizabeth Parker.I also have a Walter Dalziel in my family, born in Lanarkshire and immigrated to Canada.My family group settled in Vaughan Township now part of N. Toronto.I followed what I believe is your relative just to determine that family was not directly part of the Vaughan Township family.
The other Walter I found was Walter Dalziel listed as born in Scotland and age 52 in the 1881 Canadian Census.They settled in Medonte Township, Simcoe County near the town of Midland Ontario & farmed lot 20, concession 4 of Medonte.The wife Elizabeth was 47 in 1881 and her death was registered in Simcoe County, Medonte Township as occuring on the 23 July 1898, age 63 and stated she was born in York County.
In the 1881 census their children were: Annie - age 20, William age 18, Robert age 15, John age 13, Mary age 11, Elizabeth age 4 and Walter age 1.
I found a marriage for Walter Dalziel & Elizabeth Parker which just said that Walter was the son of James and Marion from Beverley Township and the marriage was 1861.
There is information on Ancestry.ca about this family and you can find census free on various Canadian websites.The Dalziel family still has connections in the Midland area and there are Dalziel family graves in the Midland cemetery - I think that cemetery is called Lakeview. Diane Anderson
