I've looked on FindMyPast from 1878 to 1881, and cant see any Breakingburys. The only one near it is Henry Breakenbury aged 71 Aylsham second quarter 1881 4B 56, which doesn't look likely.
Perhaps she told a little white lie and wasn't married! Have you sent for her marriage certificate to James as this will probably give her maiden name as well as Breakingbury and her father's name and you may be able to find her first marriage that way.
Good luck
