Sometimes tracking one’s immigrant ancestors tests all one’s research acumen. Identifying individuals, their origins, and parentage; tracking them through time; and constructing biographies to place them in their social context is best approached by broadening one’s approach to include family members, associates and neighbors. This presentation will outline a research program for solving genealogical research problems via cluster and collateral research techniques. Topics will include: appropriate application, research planning, commonly used resources and documents, and case studies successfully tracking individuals from Europe to the United States, overcoming name and residential changes.
