We're back ....

Hello all. I have been recently looking into my Dalgarno relatives again. I never did get much further then where I was when I left this thread last time. A couple tantalizing clues did emerge though. First a recap:
My great Grandmother was Margaret Dalgarno from Aberdeenshire. She had my Grandfather James Mutch out of wedlock on 21/05/1836 at Peterhead. The father was Joseph Mutch. On his death the cert for James Mutch says the same...born illegitimate.. it lists his mother as Margaret Smith. I know it's the correct death cert for James because it correctly lists his wife Ann Chapman.
That lead me to find the 18/11/1852 marriage of Margaret Dalgairn and George Smith. This couple had 2 kids from what I can see. George and Isabella. Then George the father dies leaving Margaret widowed in 1854.
Meanwhile I had earlier followed ancestry trees (never a good idea) and put Margaret Dalgarno's birth at 1821. Based on that I found the corresponding census entry for a Margaret Dalgarno who lived at Aughtygall in 1841 with parents James Dalgarno and Sophia Crookdhank:
1841 census:

My Grandfather James Mutch is nowhere to be found. I did some looking and found him nearby at Blackhill with a crofter named William Taylor:

I was still under the impression that Margaret Dalgarno's parents were as listed on the 1841 Aughygall census ...James Dalgarno and Sophia Cruickshank. After Sophia dies you even see Margaret Smith with daughter Isabella and father James Dalgarno labourer.

After awhile I just forgot about it until recently I got a notification that I had a new DNA relative listed.
This person was related via a woman named Jane Kennedy born about 1831 to a Margaret Dalgairn who died 1874. Parents listed as James Dalgarno and Jane Taylor. I got the death cert (attached) and it does contain that info. No mention of the name Smith. There is a big question mark so there was some confusion... She dies in Blackhill which is where James Mutch was at age 5 with William Kennedy.. The witness is a James Willox who is the husband of Jane Kennedy and it says son in law to Margaret. It also says she was 74 years old so born 1800/1801.
This Margaret fits in a lot of ways ... her age , she dies in Blackhill , son in law is the right person.
I found them in 1841 census:

Which Margaret Dalgarno is the correct one for me? How can there be a Margaret Dalgarno with daughter Jean Kennedy in 1841aged 40 and a Margaret Dalgarno living with Elspet Mutch at Autygall aged 20 and I'm somehow related to both ...
The ages given for Margaret Dalgarno who lived at Aughtygall always line up with being born about 1821. She consistently gives her age as born 1821 and lists James Dalgarno widowed labourer as her live-in father.
It gets a bit more complicated as I am also DNA related to children of Henry Flockhart Dalgarno. He is the son of James Dalgarno and Sophia Cruickshank. He was born 15/07/1828 at Peterhead. James and Sophia married 1817.
So it seems that James Dalgarno who married Sophia Cruikshank is related to my Margaret Dalgarno ...even if he isn't her father. I had thought James could possibly be her uncle but found no proof. The death cert for James Dalgarno 1787-1853 says his father was a blacksmith and his mother was Margret Ramsay whereas Margaret Dalgarno who died 1874 lists father as James Dalgarno weaver and mother Jane Taylor.
That JD and Taylor combo sounds like the one mentioned earlier in this thread and on this grave:
https://www.findagrave.com/memorial/232471357/jane-dalgarnoI believe the above James Dalgarno , wearver , was at Blackhill also in 1841:

I'm trying to tease out what goes on there with Margaret Dalgarno. Is there 2 of them or one that gives false info on censuses? Or can I be related somehow to both? Thanks in advance. I am rereading the current thread as there was a lot discussed and there may be stuff that has been already brought up.
Attached is the 1874 death of Margaret Dalgairn at age 74. Parents James Dalgarno weaver and Jane Taylor. I actually had this document years before finding the DNA relative of Jane Kennedy. I had discounted it because of the 74 in 1874 age that dated her to 1800/1801.
