I should add it to Letter from Arthur Tolkien to Mary Jane Tolkien (Stowe) • 4 January 1892 (#987) 😁

The letter is long out of copyright, being written a day after Tolkien's birth so I include an interesting quote from it that is pertinent to your post. Maybe Arthur was aware of the timings 😁

My dear Mother.

I have good news for you this week. Mabel gave me a beautiful little son last night (3 January). It was rather before time, but the baby is strong and well and Mabel has come through wonderfully.

Yes, thanks onthetrail for including the details. The evidence suggests that Tolkien was slightly premature, one of the great things about having access to our database to correct any misunderstandings. Not that it would matter anyway.
