A private owner donates "important" personal Jackie Kennedy letter to Jack, aka JFK, celebrating the birth of their first child. 

 A personal letter, written by the First Lady, Jackie, to her husband, "Jack", the then-Senator John F Kennedy, has been donated to the John F Kennedy Library Foundation by its private owner. 

The letter written celebrating the birthday of the couple's first child, Caroline, in Nov 1957, had been bought by RR Auctions House but was gifted to the Foundation last Tuesday by the company's founder and CEO, Bob Eaton, the Boston Globe reported.

The deeply personal note gives a true insight into the relationship between Jackie and her husband, the Senator. She opens with "Dearest Jack" and signs off "All My Love, Jackie".

In the three-page letter, Jackie celebrates the arrival of Caroline. She writes "at last a baby we both love.”

She also bemoans that she writes "stiff letters" unlike her husbands. She says "It is hard for me to communicate — which you do so beautifully.”

“I know everyone says married couples should never separate — as you get off the same wavelength — It is true you do — but I think it is usually good when we go away from each other as we both realize so much,” Jackie wrote to her husband. “We are so different — but I was thinking this trip — that every other time I’ve been away, you would write ‘don’t ponder our relationship too much’ etc. — [and] now I don’t, as one doesn’t ponder anything that is a part of you —”

At the end of her letter, she also reflects on how different their marriage is from most relationships.

She writes: "You are an atypical husband — increasingly so in one way or another every year since we’ve been married — so you mustn’t be surprised to have an atypical wife — Each of us would have been so lonely with the normal kind."

She adds “I can’t write down what I feel for you, but I will show you when I am with you — and I think you must know—.”

“All my love, Jackie.”

In a small ceremony on Jan 7, the letter considered an "important" Kennedy family artifact was given to the non-profit, which provides support to the library and museum dedicated to the 35th president of the United States, JFK. 

Doris Drummond, the chief financial officer of the Kennedy Library Foundation said: "It’s in the proper place, it’s in a good place."

Adding “It’s in the proper holding place, rather than being auctioned off. We appreciate RR Auction giving it to us and not auctioning it off. I think that’s such a great decision by them. It’s wonderful.”

The letter will not be on display at the museum, but will “be held by the Foundation with its historical records that are safeguarded and protected,” the nonprofit said in a statement.
