Hello Ruth,
I have some information about James Coynach you mention in Reply 4.
James Coynach/Coyndoch/Cynach/Kynoch married twice & his Death Certificate says:
James Kynoch (Married to 1.Mary Mitchell. 2.Margaret Milne) died 17th Aug, 1891 at Bush Cottage, Gordons Mills, Old Aberdeen age 79yrs. Son of John Kynoch (Master Tailor) & Janet Kynoch ms McKenzie. Informant was Alexander Massie, Son-in-law. [168/04 0027]
I've not found a marriage for James & Margaret Milne but 1851 Census they are at Westerton of Invereddie, Longside.
James Kynoch 37 b Peterhead.
Margaret " 38 b Longside.
Margaret " 9 b Old Deer.
Younson " 2 b Longside.
Not found a birth for dau Margaret, but I think she is the 2month old Margaret Coynack on 1841 Census with James & Mary (Mitchell)
(Younson/Youngson Coyndoch, son of James Coyndoch & Margaret Milne, was born 4th Feb,1849 at Longside)
1861 Census. Todholehills, Longside.
James Cynoch 48 Farm Servant b Inverness? Boarding with employer Alexr. Keith & family, while wife Margaret Coynock 48, Youngson 12 & dau Hellen are at Nether Kinmundy, Longside.
(Helen Barron Coyndoch, dau of James Coyndoch & Margaret Milne was born 16th Jan, 1853 at Longside)

James Kynoch 59, Margaret 58, Youngson 22, Hellen 18 & G.dau Hellen M[assie] Kynoch 6months.
1881 Census. School Lane, Old Machar.
James Kynoch 71, Margaret Kynoch 68.
1891 Census. Bush Cottage, Old Machar.
James Kynoch 79 & Margaret Kynoch 78 are living with daughter Helen & son-in-law Alexander Massie. (Informant on James' Death Certificate)
I'm afraid I don't have any information about Mary Mitchell or James & Mary's children. I assume Mary died 1841-1847. (Only found 1841 Census today, thanks to your post)
Youngson Kynoch emigrated to USA & died there in 1924 aged 75yrs. Dau, Helen Massie ms Kynoch died 1926 in Old Aberdeen aged 73.
Margaret Kynoch, Widow of James Kynoch died 12th June 1897 at College Bounds, Old Aberdeen age 85yrs. She was born 3rd Apr 1813 at Longside to John Milne, Crofter & his wife Jane/Jean Smith, who were my husband's 2xG.Grandparents.
