Hi John, Some members of our family did immigrate to Australia, starting in the early 1800's. Although variations exist, the more common spelling of our name there seems to be "Northrope". There are some great stories in the family records about their early days "down under."
"Stanley" was not a common name in these branches of the family (that's good!). One of the "Stanley N.'s" born about this time was Irving Stanley Northrop (b. 30 January 1890 in Huddersfield, Yorkshire, England; d. Abt. 1964 in Auckland, New Zealand). For safety and security, it was common for families to move with and live near their relatives, and often our family members gave the surnames of the mother and/or grandparents, and/or favorite aunts, uncles, etc. as middle names to their children. And frequently other favorite family names were handed down to the grandchildren, etc. Send me an email, and we can compare more notes to try to discern where your family connects to the main family lineage. Best regards,
