How should siblings index the records connecting each person to the relevant parent?
Build a sibling evidence tree with a separate documentary connection for each person and each relevant parent. The tree should expose missing links and later civil changes, not simplify them away to produce a cleaner picture.

Build two documented paths to the relevant parent
Sibling evidence involves more than demonstrating that two adults have similar names. The I-130 checklist identifies birth certificates for the petitioner and the sibling. In a working family tree, draw a separate path from each person to the relevant parent or parents, then identify the civil record supporting each path. This structure makes it easier to see what the documents establish and where additional history needs review. It also avoids treating a photograph of a large family or an informal declaration of kinship as a substitute for the actual civil-record connections.
Keep each sibling's civil record independent
Create individual entries for the two birth records, including the recorded names, issuing authorities and any amendments. Do not merge their contents into a single rewritten family narrative. One certificate may have been registered or reissued much later than the other, and the documents may use different scripts or naming conventions. Those differences are information to preserve. An example index can put the event date and the document's issue date in different columns so a reviewer does not mistake a recent certified copy for evidence that the birth itself occurred recently.
Add intervening family events to the diagram
A family diagram may need to show different marriages, parental name changes, adoption records or other legal events between the two birth entries. Keep each event attached to its own document and retain the record's actual terminology. A later marriage certificate and an adoption order serve different functions even if both help explain why names differ. The diagram should not decide which legal category applies to a complex relationship. Its purpose is to expose the sequence and provide a navigable route back to the records a qualified reviewer will need to interpret.
Explain differences in parental names and registration dates
When the same parent appears under different names, identify the exact variation and the source that connects the versions. A translator's consistent rendering can make a package easier to read, but it cannot establish that two differently named individuals are the same person. Provide the translator with relevant source records and preserve any notes distinguishing spellings. If a certificate's reverse side carries a correction or annotation, include it in the source inventory. Omitting that page can remove the very information needed to understand the connection shown on the diagram.
Test every connection before using the family tree
Review the completed tree one connection at a time. Each person should point to a source, each legal event should have a date and issuer, and any unsupported link should be marked as a question. Avoid expanding the diagram with unrelated relatives merely to make the file appear more complete. Compare the proposed evidence with the current instructions for the actual petition and keep document selection separate from the preliminary research drawing. A useful tree is concise enough to follow while retaining the detail needed to investigate a contested or unusual family history.
| Record group | Question to review |
|---|---|
| First sibling record | Identify the parent information in the first person’s civil record. |
| Second sibling record | Preserve the corresponding information for the other person. |
| Shared-parent linkage | Connect the parent’s identity across names and dates. |
| Later legal events | Keep adoption or stepfamily or other relevant changes separately documented. |

Common questions
Does a family tree replace civil records?
No. It indexes the claimed links and should point back to the underlying source for each connection.

How are half-sibling records organized?
Preserve each person’s actual parent information and the shared-parent identity chain without assuming a legal result.

Should a stepfamily event be hidden to simplify the diagram?
No. Record relevant legal events accurately and leave their immigration effect for qualified review.
Sources: Policy Manual: evidence
Why keep each sibling’s record separately?
Separate records let a reviewer verify each connection instead of assuming that one person’s document establishes the other’s history.
