Jane can trace her ancestors back as far as 1786. There are four complete generations on her father's side and three on her mother's, a total of 22 persons. All of her known ancestral lines begin in Prussia. About half the surnames are German; the other half, Polish.
The ancestry report uses 'Ahnentafel' numbering. This means that the numbers for a person's parents will be twice as large as that person's number. For example, if a woman's number is 15, her father will be number 30, and her mother will be 31. Her child will be number 7.
