A CREWE mum who launched a social media appeal to find a mystery train passenger who passed her a £5 note and a letter describing her as a ‘credit to her generation’ has been reunited with him.

Sammie Welch, 23, from Crewe, launched a social media campaign to find the generous stranger who handed her a £5 note and heart-felt letter when she was with her three-year-old son Rylan.

The man handed Ms Welch the letter, which was signed simply ‘Man on train at table with glasses and hat’, as he got off at Bristol.

The mystery man was unveiled as Ken Saunders, 50, from Wiltshire, and the pair were reunited on ITV's Good Morning Britain.

"Thank you so much," Ms Welch told Mr Saunders on ITV's Good Morning Britain. "I don't think you realise the impact you actually had and what you actually did for us.

"I think I looked shocked at first because I couldn't believe it and then I was looking for you and I could only see my own reflection in the glass."

Ms Welch social media campaign created a whirlwind of media attention in the few days that followed the incident.

Ms Welch, who now lives in Plymouth, Devon, said she ‘wanted to cry’, and appealed on Facebook to let the man’s identity known so she could thank him personally.

She said: "He shows there are still good people out there and I want him to know I am truly grateful."

The handwritten note read: "Have a drink on me. You are a credit to your generation, polite and teaching the little boy good manners.

"PS I have a daughter your age, someone did the same for her once. Hope when she has children she is as good a mother as you.

"Have a lovely evening."

Speaking on Good Morning Britain, Mr Saunders said the generous gestures a simply ‘a spur of the moment decision’.

"She came on, the little boy was a bubbly little boy and he coughed and she said 'oh Rylan, put your hand in front of your mouth' and then he practised it quite a bit after that,” he told presenters Susanna Reid and Ben Shephard.

"He coughed quite a bit and put his hand in front of his mouth and then he said 'what' and she said 'no, pardon, Rylan'.

“It was quite funny. It was entertaining. It was all just very endearing, and I just thought it was wonderful. Youngsters today are much maligned and I thought here is a great role model, great mother and I just thought this is lovely.

"As I got towards Bristol I took my ticket out and there was £5 note and a scrap of paper and it was just a spur of the moment thing.

“I thought I'm going to tell her what a great mother she is and put a smile on her face."
