I've come across further information after getting some certificates from NZ B,D&M. A death certificate for Agnes and her son David's birth certificate - I thought I'd fish for information from a few different angles. She was born in Hamilton, Lanarkshire, Scotland, about 1851. Her Father was called William Maxwell and her Mother was also called Agnes, formerly Maxwell as well. I cannot find any information about a William and a Agnes together in Lanarkshire, Scotland. Any information provided would be great fully appreciated. Jamie
