Since 1935, American Research Bureau (ARB) has specialized in international genealogical research, heirship determination, and the location of missing and unknown heirs to foreign and domestic estates. When ARB contacts you, we believe you may be entitled to an inheritance we have identified. ARB’s worldwide team of professional genealogical researchers and investigators can assist in all aspects of probate research. ARB assists courts, estate lawyers, executors, and trust companies in locating missing and unknown beneficiaries. ARB has been screened, approved, and accredited by the Better Business Bureau.
