I would ask if any forum members might be able to recommend a firm to assist. Our thinking is an English speaking Polish researcher.
We are dealing with an intestacy (England) however there are entitled beneficiaries from the paternal Polish side of the family. We have basic details (names / locations / approximate dates of birth) however we need to evidence the Polish family, ideally to include copies of relevant birth, marriage and death certificates including certified translations of same.
Should you need additional help on this matter our firm has links with researchers in Poland. They have been most useful with genealogical matters we’ve had in the region.
