Aisling Brady McCarthy, the Irish nanny who was wrongfully charged with killing a one-year-old child in her care in Boston, is back in Ireland and very much enjoying her freedom.

For instance, celebrating her wedding anniversary with her husband, Don, in person for the first time ever.

Don McCarthy, from Cork, and Aisling Brady, from Cavan, were wed in Massachusetts just four months before she was arrested in connection with the death of Rehma Sabir, the little girl in her charge.

McCarthy, now 37, then spent two and a half years in prison and close to five months under house arrest as she awaited trial.

After being acquitted of all charges at the start of September, following the release of new evidence from the Middlesex County Medical Examiner, McCarthy returned to Ireland with Don, just in time to celebrate their third wedding anniversary.

“It was hell for Aisling but it was also hell for Don. Don has stood by her from day one and supported her,” Aisling’s sister Sharon Grehan told RTE Prime Time.

Grehan traveled to Ireland with her sister – who had been in the US illegally at the time of her arrest – but has since returned to Boston, where she resides.

"Aisling is doing amazingly well, despite what she's been through,” Grehan shared.

"I mean she's been through hell. What happened [to] her was terrible. It should never have happened. But she's enjoying her freedom. [She’s] Enjoying the time with her husband.

"She needs her space but she is doing well. She's a strong girl."

Grehan also recalled how hard it was to visit her sister in prison, and to leave here there knowing she was innocent.

"It was tremendously difficult. My brother Raymond is also here in Boston. And he shared the burden of the visits and Don also, Aisling's husband,” she said.

"We had wonderful people help out with the visits. Going into that prison and seeing your sister in there was just terrible.

"The fact that you had to leave her there after a visit, knowing that she did nothing wrong.”

Aisling and Don are now recovering in her hometown of Lavey, Co .Cavan, in the company of their extended families.
