My great grandfather Samuel Revell Hirst was born in 1848 in Harewood, West Yorkshire, UK. According to UK Census data, his wife Sarah Elizabeth was born in Delaware USA in about 1850. They had 5 children; firstborn was Samuel Revell Hirst b1874 in Philadelphia USA. Unfortunately, his baptism at St. Mark's Church in Philadelphia was not recorded. Birth certificates of the other 4 children, who were all subsequently born in the UK, show their mother's maiden name to have been Spence.
I would much appreciate any information regarding Sarah Elizabeth Spence's origins and if/when/where she married my great grandfather.
