Linen Hall Library, Belfast. I have an index to just one of their collections, the Blackwood Family history manuscript Trees which are mostly Co Down families. My result for your surname is ………………….. I suggest you ask them for photocopying estimates if they think your knowledge relevant and be prepared to pay the extra for post and packing. However if the material is really relevant when you get it, I suggest a further donation to this unique library that is always needing extra funds.
