I tried picking apart the info about Dorothy Davis and Percy Samson, to see if I can match them to the 1935 Newfoundland Census, or rule out a match.
Here's Dorothy's death certificate from North Carolina, which matches the parents and dates in the first answer:
"North Carolina Deaths, 1931-1994," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:FGZ4-GL1 : 18 July 2017), Dorothy Davis Samson, 26 Oct 1988; citing Pinehurst, Moore,North Carolina, cn 45903, State Department of Archives and History, Raleigh; FHL microfilm 1,991,470.
Pearce/Percy Samson died in Florida, also in 1988:
"Florida Death Index, 1877-1998," database, FamilySearch (https://familysearch.org/ark:/61903/1:1:VV48-D12 : 25 December 2014), Pearce Samson, 02 Feb 1988; from "Florida Death Index, 1877-1998," index, Ancestry (www.ancestry.com : 2004); citing vol. , certificate number 12059, Florida Department of Health, Office of Vital Records, Jacksonville.
Their FindAGrave memorials show them buried together with a shared headstone.
Percy came to the US in 1927, and was still single in the 1930 Census:
"New York, New York Passenger and Crew Lists, 1909, 1925-1957," database with images, FamilySearch (https://familysearch.org/ark:/61903/1:1:KXLW-KL8 : 12 March 2018), Percy Samson, 1927; citing Immigration, New York, New York, United States, NARA microfilm publication T715 (Washington, D.C.: National Archives and Records Administration, n.d.).
"United States Census, 1930," database with images, FamilySearch (https://familysearch.org/ark:/61903/1:1:X4LV-LLD : accessed 6 May 2020), Percy Samson in household of Freeman Butt, Brooklyn (Districts 1501-1750), Kings, New York, United States; citing enumeration district (ED) ED 1633, sheet 11B, line 66, family 159, NARA microfilm publication T626 (Washington D.C.: National Archives and Records Administration, 2002), roll 1516; FHL microfilm 2,341,251.
Here are Percy and Dorothy in New York in 1940, with three children, the oldest (Max) born in New York about 1935:
"United States Census, 1940," database with images, FamilySearch (https://familysearch.org/ark:/61903/1:1:KQLT-95Z : 18 November 2019), Percy Samson, Assembly District 12, Brooklyn, New York City, Kings, New York, United States; citing enumeration district (ED) 24-1383, sheet 9B, line 78, family 184, Sixteenth Census of the United States, 1940, NARA digital publication T627. Records of the Bureau of the Census, 1790 - 2007, RG 29. Washington, D.C.: National Archives and Records Administration, 2012, roll 2582.
The record for both of them states they lived in the same place in 1935. I could not find a marriage record.
So: Dorothy who died in 1940 was definitely not the same Dorothy in the first answer. It's not impossible that Dorothy in the 1935 Newfoundland census is the same Mrs Samson, but I think she would have to have been pregnant with Max already. Overall, I'd say the timing favors Dorothy Davis Samson being an entirely different person, and 1935 Dorothy Davis is the Dorothy who died in the same town in 1940.
I hope that helps you work out which Dorothy is the one of interest, and gives you a bit more to go on.
Good luck!
