I guess the thing is that there is no question raised in this thread about the Clezie side of this family. The question in this thread and the numerous others on the same subject is about Ellen Lockhart.
I said:
In this particular case, there isn't really any Clezie in NY state -- just James Clezie who went there from Toronto and married Ellen Lockhart. And disregarding that I said "in this particular case", i.e. in the case of James Clezie and Ellen Lockhart, you replied:
Yes, there were some. George Oswald Clazey, married to Margaret Hall, is in the 1850 census in Carmel. George and James were first cousins; their fathers were brothers. Yes, that's interesting, and as I said:
they could have been related back in Scotland.
Because
in this particular case, the family of James Clezie was settled in Canada by 1840, and his parents remained there, and his siblings are accounted for, and none of them is in NY state ever.
You say:
I see no evidence that Ellen was part of this family.And again, I suggest you read at least this thread, if not the others. No one has suggested there is PROOF of her connection with the family. There are numerous indications of a connection, in particular the fact that the names of the two of her children that are otherwise unaccounted for were the names of the Lockhart/Henderson parents of, apparently, all the other Lockharts of the same generation in Rensselaer County c1840-1855.
"Proof" would be a birth record in Scotland that could then be somehow established to be the birth record of this Ellen. Even if a birth record that fits were to be found, that could not be done, as there is apparently nothing on any other record of hers, i.e. marriage or death, that states her parents' names or a definite birthdate or place. One could only hope for her to turn up as witness on someone's marriage certificate, or informant on a death certificate, or the like. But that is unlikely to happen, as the family scattered, with some concentration in Chicago, and Jane and James Clezie were never there.
The fact is, however, that there are no Scottish birth/baptism records that can be found for
any of the children in this Lockhart/Henderson family, not one of them (and for the one born in Canada, it was before records are available).
If Ellen did belong to that family and happened to have stayed in Canada when the family left for NY after the birth of Robert, if that was what happened, which seems to have been in 1836 (Robert's date of immigration to the US, from the 1900 census), when Ellen would have been about 20, then there will be no record of her in the US if she and James simply travelled to Rensselaer County to marry because that was where her family was. There would be no record of a young single woman, likely a domestic servant, in Canada, before 1840.
Ultimately, there may simply be no record anywhere that will establish who Ellen is. All we have now is the hypothesis that she was a daugher of William Lockhart and Margaret Henderson, because all of the available facts fit that hypothesis and none of the available facts refute it.
Perhaps you can do better, though! As I said, several of us are still interested.

I trust you have noticed by now (re your quoting of the request for proof of James Clezie's parentage) that there really is no question here on the Clezie side.
TMS, you are replying to things completely pointlessly and just cluttering the thread with repetition. For one thing, it has been established that Elexis and the entire Lockhart family in Lanark County, Ontario, are completely unrelated to this query.
