Archbishop of Canterbury Justin Welby's daughter finds love after heartache Katharine Welby, who has spoken about the heartache that she suffered in her love life, has reason to smile. Mandrake learns that the daughter of the Archbishop of Canterbury, the Most Rev Justin Welby, is engaged. Her boyfriend, Mike, an IT consultant, proposed on Saturday. "I am so excited," says Katharine, 26, who sent friends a photograph of her wearing her engagement ring. She could choose to have a double wedding ceremony with her brother, Peter Welby, who became engaged to Jen Bates this summer after his return from strife-torn Egypt, where he studied Arabic for two years. Bravely, Katharine spoke out about the depression that had driven her to the brink of suicide last year. The end of her previous relationship was the final straw. "My whole life fell apart," she told The Sunday Telegraph. I got to the point where I just couldn't bear the thought of living any more.
