About ByLineage
A family story is not yet a citizenship case
ByLineage helps you put the people, dates, citizenship events, and records in the right order before you decide what to do next.
Why does ByLineage exist?
The question often sounds simple: "My grandparent came from this country. Can I get citizenship?"
Short answer: it depends.
A birthplace, surname, old passport, or family tree may help you start. But it may not show whether citizenship passed to the next generation.
You need to check who was a citizen, when each child was born, and whether a registration, naturalization, marriage, adoption, loss, or border change affected the family line.
ByLineage exists to help you organize that work. Start with the facts that can change the answer. Then look for the records that prove them.
What do we check first?
You do not need to order every family document before you understand the question.
- 01
The closest connected ancestor
Who was connected to the country, and were they actually a citizen?
- 02
The citizenship dates
Was each parent already a citizen when the next child was born?
- 03
The events that may change the line
Naturalization, registration, loss, marriage, adoption, or a territorial change may matter.
- 04
The records you already have
We separate useful evidence from documents that only provide a research lead.
How do we work?
One country and one family line at a time.
- 01
You explain the starting point
Tell us the country, the closest ancestor, and what you already know.
- 02
We put the events in order
Births, citizenship events, and family changes go into one chronology.
- 03
We identify the possible process
The case may involve proof, registration, restoration, naturalization, or a separate legal review.
- 04
We define the next useful step
That may be a record search, a document review, or a discussion with an independent specialist.
When does a specialist need to review the case?
Some facts cannot be reduced to a short form or a family-tree calculation.
