Hello,
William Grier and Mary Ann Buchanan are my GGG Grandparents. I am descended from their daughter Mary Jane, who emigrated to Australia before 1872 (she was born in 1851), I am taking the spelling of Grier from Mary Jane's marriage certificate, where she spells and signs her name 'Grier', although I have seen other documents with 'Greer'. Judging by her signature, she was educated, as it is accomplished penmanship for the time.
I am hoping to track down William and Mary Ann's marriage certificate, but so far no luck. I am happy to share any documents with you.
Regards,
Rosemary
