I've been researching a family line and I've run into a wall because this particular many greats-grandmother had all her children years after her husband died. She never remarried, but she used her married name for all her children as well as their fathers on their birth records. So I have a (hopefully) correct first name, and occupation, and area, but no last name. Is there a way to search for Bricklayers in Marylebone, Middlesex, England in 1860?
