Birth of Albert Crow
In records from birth (recorded from doctor but births were at home and not recorded on the dates of birth) it lists the month of birth as 23 May 1853 but on Albert's tombstone it records his birthdate as 23 Jun 1853.

So day and year are the same but month is different.
Not sure where the mistake is made.
