I have added some sources for William Marshall, Free Settler “Persia” 1863. These suggested only minor changes to the profile, so I went ahead and made them.
But a confusion has arisen concerning dates of birth for him and for his children. I calculated their dates of birth from their ages given in the immigration document for his family arriving in Sydney, Australia aboard the "Persia" on 1863-05-10. That document says William came from Rothes, Aberdeenshire, and that his children were natives of Rhynie, Aberdeenshire. So then I searched at ScotlandsPeople and found birth records for them with slightly different dates. Here are the details:
[[Alexander Marshall, Free Settler “Persia” 1863 Alexander Marshall, Free Settler “Persia” 1863] William Marshall Snr]:
Immigration date: 1836 (ie. 1863-05-10 - 27)
ScotlandsPeople: 1834-12-30 birth record for William Snr
[[William Marshall, Jr William Marshall, Jr] William Marshall Jr]:
Immigration date: 1859 (ie. 1863-05-10 - 4)
ScotlandsPeople: 1858-10-24 birth record for William Jr
[[Alexander Marshall, Free Settler “Persia” 1863 Alexander Marshall, Free Settler “Persia” 1863] Alexander Marshall]
Immigration date: 1861 (ie. 1863-05-10 - 2)
ScotlandsPeople: 1860-01-08 birth record for Alexander[[John Marshall John Marshall] John Marshall]
Immigration date: 1862 (ie. 1863-05-10 - 1)
ScotlandsPeople: 1861-11-23 birth record for John
I'm a bit confused about these differences, and I'm wondering if any of you have experience with calculating ages in Scotland in earlier centuries.
The online age calculator is an easy way to find someone's age on a particular date from the date of birth, and for these people gives these results:
William Marshall Snr: 28 years 4 months 11 days, not the 27 in the immigration record,
William Marshall Jr: 4 years 6 months 17 days, which matches the age in the immigration record
Alexander Marshall: 3 years 4 months 2 days, not the 2 in the immigration record
John Marshall: 1 years 5 months 17 days, which matches the age in the immigration record.
The notes at the online age calculator say that ages are calculated differently in different cultures, and I'm wondering if any of you have experience with methods used in Scotland.
Thanks for thinking about these things.
Things to consider when looking at early Australian immigration records
In my research I have one gentleman who was a very successful businessman and travelled every year on holidays - he always had the same family with him and provided his home address and the names of who he was travelling to so I know the records are all him. I have in excess of 30 travel documents for him and his age and date of births changed constantly.
