You are helping me format my family-history research so it can be bulk-imported into
MyAncestors. Convert the research I give you into the MyAncestors Import Format (MAIF)
EXACTLY as specified below. Output ONLY the formatted text — no commentary, no code fence.

RULES
- One block per person. Begin each block with a line that is exactly:  --- PERSON ---
- Under each block, use `Label: value` lines from the list below. Omit a label if you have
  no value for it. NEVER invent facts — anything uncertain goes on an `Unverified:` line, and
  set Sex only when the source states it.
- Names in Parents / Spouses / Children / Siblings are plain names — the reviewer links them
  to real people in the tree later, so you do not need ids.

LABELS (use these exact labels)
  Name:            (required) the person's full name
  Nickname:        a nickname, if any
  Maiden name:     surname at birth, for someone recorded under a married name
  Sex:             M or F — only if the source states it; otherwise leave blank
  Born:            date | place      (e.g.  5 Jun 1796 | Bedford Co., PA  — either side may be blank)
  Died:            date | place
  Parents:         comma-separated names
  Spouses:         comma-separated names
  Marriage:        spouse | status | date | place   (status: married / divorced / widowed / separated /
                   partners / unmarried / unknown; repeat the line once per marriage)
  Children:        comma-separated names
  Siblings:        comma-separated names
  Confidence:      A, B, or C — how well the records back this person. A = documented / primary,
                   B = corroborated secondary, C = compiled or tradition. Use the word "weak" if the
                   source itself flags the link as unproven (it becomes C plus an "unverified" flag).
  Flag:            type | note   — a caution to surface in the tree. type is one of:
                     warning     (a source caveat, e.g. "these children are attributed, not proven")
                     structural  (an open question about the tree's shape)
                     general
                   Repeat the line for more than one flag.
  Note:            free text. Put burial, baptism, and occupation here for now, e.g.
                     Note: Buried: Providence Cemetery, Elkhart, IN
                     Note: Occupation: worsted dyer
  Source:          where this came from — a citation. Repeat for more than one.
  Unverified:      something that needs verification — never state it as a fact. Repeat as needed.

OPTIONAL FILE HEADER (before the first --- PERSON ---)
  maif: 1
  tree: <a name for this batch>
  default-source: <a source to apply to anyone with no Source line>
