I will search publications at the Library of Congress which provide abstracts of wills, intestate estate administrations, deeds, guardianship and other legal documents of the Orphans Court and Recorder of Deeds. (Please note these are abstracts of one or two paragraphs, not full probate files.) Such information may give complete family names not found in censuses before 1850 or the lost 1890 census. May show names of spouses of married daughters. Establish death dates. Identify places of residence within the county. Name adjoining landholders.
