Jessie,
If your MacKinnons arrived in Canada by the 1820s then I have no info. which would help (sorry)!
I haven't done DNA as I find it a bit complicated...
As far as I'm concerned any DNA match would be with someone of this era but to follow others trees is a bit of a gamble (to me) as people can get the wrong info. then add it to their trees which means errors along the way as the DNA can't trace
exactly who you're related to i.e. each is relying on each/all having followed & found the correct info. with a paper trail initially.
That's my view (sceptical) as I've seen so many errors on trees with my own direct paternal line it's put me right off (a lot copied which is all wrong)!
I have all the certs. & census' needed & I'm not desperate to get as far back as possible without records/evidence or very good circumstantial evidence to be honest.
In my view, if they can't use the official records which are available online albeit at cost then it doesn't interest me at all.
I'm curious now as to how you came to the Currie connection in the 1st place, was it through DNA?
Sorry to be upfront but I'm more interested in genuine info. to help me & if I stay stuck in the mid to late 1700s or with one in particular (my Currie line) born c1800 or likely prior if I go by dates for his wife then so be it

He died pre statutory records i.e. no DC for parents names sadly as the name is very common on Uist

Add...I found a 'supposed' connection not too long ago with someone who had all my family (direct paternal line) in their tree yet it didn't match my docs!

I sent a message to enquire the connection & the person had added my info. as the names/dates were similar!!!

Many miles away from where my family were born/lived/married/died (apart from my g g/father who moved) & on every census.
The person was adamant my family was theirs i.e. I wasn't happy as I said I have all the docs. so I actually used my own credits on SP to find the correct info. for this person &
their family!
I have to say I got a nice apologetic reply with a 'thanks' & the person admitted following links without checking which I did appreciate as being truthful is far better than being in denial or just name collecting.
I can't believe people think they can do their family tree without evidence of
any kind
