Sometimes if an ancestor sibling goes missing, and I know their birthplace, often I do a search 5 years of their birth year, and type birthplace ie any Ann born 1820-1830 in Prittlewell, Essex and this is a good tool, often it has helped. I know birthplaces can be mistranscribed as much as names but such methods pay dividends.
Ann Musgrave born 1826 in Hurworth, Durham, vanished after 1871 but I typed in any Ann;s born 1821 to 1831 in Hurworth and memorised the results, and found an Ann Musgrave wed Thomas Glendenning in 1873 in Durham. Ann was the sister of my ancestor who emigrated to America in 1886 to join a daughter out there.
