I can't produce a reliable summary here: the "article text" provided is actually just the Daily Mail homepage's list of unrelated headlines (other stories, navigation links) — it doesn't contain any actual content about Eleanor Ekserdjian or Sam Chatto. There's nothing in the text about her background, the engagement, or the family connection to summarise.

Could you provide the actual body text of the article, or try re-fetching the URL? I'd rather flag this than invent details about a real person's life.
