Thanks for your reply, Lodger.
So I am related to your nephews then! Archibald Halliday (who m. Marion Penman) was the brother of my 4x great grandfather Robert Halliday 1781-1851 (who m. Margaret Williamson). In some censuses the two families lived very close to one another.
There appear to be more records for Arch' & Marion's children than for Robert's - I've only managed to identify 4 with any certainty, including my 3xgg John (m. Eliz. Dick), Agnes, Thomas (m. Marion Brownlie - they immigrated to Canada but have one child buried at Cambusnethan), and Violet who died fairly young (and possibly the other Robert who also died 1851 but I'm not sure).
So maybe the Halliday grave marker identified in the Old Carluke burial ground belongs to these 2 Halliday families collectively. Archibald died in 1840, 11 years before his brother. In any event, Robert "Hallowday" was apparently buried in Carluke as was his daughter Violet, so likely others of that family as well, including my John (1804–1853) and at least some of his children.
I've not found siblings for Arch and Robert, both born in Killin, Perth to Thomas Halliday and Anne Campbell... I wonder if your nephew has had better luck!
In the past you shared the Halliday related burials in Cambusnethan (mostly Arch's family group, but a few connected to John's and Elizabeth's children as well. I those have been really helpful!!
You mentioned that 'there are a few Leggat's in Cambusnethan cemetery, also in the old burial ground adjoining the cemetery and in the small private burial ground there. Also in the ancient Cambusnethan churchyard at Kirkhill."
John's daughter Agnes Halliday married James Leggat (1841-1921) that's where Leggat fits into the picture! Although they migrated to Cumberland, after Agnes died, he returned to Wishaw where he was born. I don't know where he was buried.
As far as I know his parents James Leggat and Jane Frew both died in Dalziel (in 1880 and 1901 respectively) So I guess those dates are too late for the old burying ground?
James sr. was born around 1816 (possibly Cambusnethan) to yet another James Leggat, a soldier, (variant spellings abound) and Janet Gilchrist. I don't know when or where those two died but I figure Dalziel or even a Cambusnethan area cemeteries are possibilities. I only have their names because of James (1816-1880)'s death record, so I don't know if he had siblings but I figure I probably did. In short, I'm still very much in the dark about this generation!
BTW I have been able to identify the parents of the Catherine Frew Liddell buried in Dalziel - they were Robert Frew and Mary Hunt... no direct connections to my Frew line... yet!
I suppose there must be quite a few old cemeteries that I know nothing about ... I'm still trying to get a handle on all then names of villages that crop up in my family's records - It's hard to get a sense of it all from across the ocean!!
As always, thanks for your help and also providing an opportunity to share information on the forum!!
