We have thousands of combined professional research hours, all of which are billed hourly, never on a contingent basis. Our cases have involved research throughout the United States as well as in Belgium, the Czech Republic, Germany, Hungary, Ireland, Italy, Serbia, Slovakia, Switzerland, and more. Our reports and affidavits have been accepted in New York, Vermont, and Massachusetts courts for a decade. Here are just a few sample cases we have solved:
- Traced the family of an New York City Slovakian immigrant with no known living relatives through fifteen different countries, using documents written in seven different languages, resulting in two living first cousins once removed in Switzerland
- Located seven grandnieces/nephews and five great-grandnieces/nephews as heirs in order to quiet title for a real estate title insurance company
- Found forty-nine nieces and nephews of a WWII soldier, for just one of more than 100 completed military repatriation cases
- Reviewed research and identified missing information in a case that was completed by an heir search firm, in regard to a Massachusetts decedent with heirs in Germany
- Verified the deaths of three unrelated remaindermen beneficiaries to a trust, given only their names and 1960s addresses, and located their heirs
- Documented the death of one witness to a will, and found an address for the other witness, starting with only their 1981 locations
