Hello - I've looked at this family today because I have Wyllie ancestors and someone in our Wyllie research group asked me to help with this. I sure wish that I had started with RootsChat since I seem to have reinvented the wheel a bit. Here is what I have -
David Donaldson Wyllie, Statutory Death Record 610/A 40. 1 Oct 1946, Old Cumnock, Ayr(shire). His age looks like 66. Occupation stone miner. Married to Mary Campbell. Parents "Jeanie Wyllie, domestic servant, afterwards married to 1st William Roberts Mason's labourer, 2nd James Smith Coal Miner (deceased). Informant David Wyllie son.
David Donaldson Wyllie, Statutory Marriage Record 610/A 36. 1902 7th November, Old Cumnock Ayr(shire). St John Chapel, Cumnock, Roman Catholic Church. His age 19, coal miner bachelor. parents "Jeanie Wyllie (was married to William Roberts Mason's Labourer)". Mary Campbell, age 17, domestic servant (spinster) parents Thomas Campbell Pit Foreman & Susannah Campbell MS Mc Gunn. Usual residence for both of them is Elbows Lane Cumnock. David signed with "X" his mark.
Thomas Donaldson Wyllie, Statutory Birth Record 586/1 69. Sept 25, 1913, Dalmellington Ayr(shire)
parents David Donaldson Wyllie coalminer & Mary Wyllie MS Campbell, married 1902 Nov 7th Old Cumnock. Address High Street Dalmellington
I've looked at a number of David (Donaldson) Wyllie births circa 1884 but none match with his mother's name. He appears to be illegitimate, but that was required to be noted in Death Records until into the 20th century but I can't recall when that was dropped.
I couldn't find his mother's marriages but I was guessing at the years. It looks like she divorced her first husband since the records don't say he is deceased.
I think that I found William Roberts + Jeanie in the 1901 census. Elbow Lane, Old Cumnock, and he is a mason's labourer. I just have the ancestry transcription so the ages are suspect. The oldest child is 17-yr-old David Roberts "son". I wonder if that's David Donaldson Wyllie. Birthplace is Glasgow and occupation Miners labourer. There are three younger children: Mary (19), Henry (5) and Jeanie (3). The younger children were all born in Dumfries. William born England and Jeanie born Glasgow
The 1891 census: I found a Willm and Jane Roberts in Dumfries. The birthplaces for them are correct but the ages are odd so perhaps mis-transcribed. He is a hawker. The children are Daniel Roberts b. Glasgow age 5 and Willm Robert age 2 b Annan. So either David does not appear here, or Daniel is actually David, or this is a doppelganger family just out to confuse us.
I had a look for Jeanie Wyllie in the 1881 census, looking for her as a young domestic servant, born Glasgow. The LDS 1881 census has a Jeanie Wylie, age 18, domestic servant, b Glasgow, in Alloa Clackmannan, head of household Janet Younger age 58.
I'm happy to try to help sort this all out.
