Tracing Equines

Hi I am trying to trace a foal which my mare had back in 2012. I sold her at Cavan horse sales in Ireland when she was a 2 year old filly, grey in colour, microchip number 372141407004427. It was on the 31/10/2014, docket number 19425 Lot no. 5. The name I have who bought her was a T. Lancaster. The mare that had her unfortunately died last month at the grand old age of 32, I had her with me for 20 of those years and had a great time with her. This is just a shot in the dark to see if there is any chance that I might trace the foal which is now 10 years old. If anyone out there knows of this horse or of Mr T Lancaster would you please send me details of how to get in touch with them. Any help will be much appreciated. Thank you to all who will read this.
Regards Heather
