The pattern of not recording births on time, or late by some months or years, that was practised in the old country continued into the new country, because our ancestors were distrustful of authority and the constant fear they may be asked to move on, or be arrested etc for whatever reason.
My Abrahams/Abrams (formerly Ceglaski) great grandparents came to Manchester, UK in 1867 from Suwalki, and eight of their nine children were born in Manchester. These children were all given certain dates of birth on their official birth records which in every case were completely at odds with the birth records given in their official school reports, and it may be that neither were correct. My grandmother Hannah always told her family her birthdate was 31st October 1875, but her English birth record gives it as February 1876. Her school records give another date again in between the two.
On my Guttenberg (later Graham) side, where my great grandfather Aaron came from Rajgrod to Hull in c 1865 to avoid the Tsar's draft, the birth of one of his sons was announced in the Jewish Chronicle at least one week before the date given on his official birth record. I never got to grips with the date on which Aaron was born as it was given in various Polish and other records any time between 1844 and 1850. As he had a wife and baby daughter when he came to Hull, it was unlikely he was born as late as 1850.
In the records on JRI Poland, I had problems working out if my great grand uncle Barnet Servian ne Baruch Serwianski from Sejny was born in 1855 or 1859. It transpired he was born in 1855 but his birth was registered in 1859.
