Are Lilibet Diana Mountbatten-Windsor and Archie Harrison Mountbatten-Windsor biologically Meghan Markle's children?

1. What the mainstream records say — parentage as stated

Authoritative public summaries and long-form profiles consistently list Prince Harry and Meghan Markle as the parents of Archie and Lilibet. Encyclopedias such as Britannica identify Lilibet as “the daughter of Prince Harry, Duke of Sussex, and Meghan, Duchess of Sussex” ^[4] and Archie’s entries likewise describe him as “the son of Prince Harry, Duke of Sussex, and Meghan, Duchess of Sussex” ^[3]. News outlets and official royal statements at birth likewise tied each child to the Duke and Duchess ^{[5] [6]}.

2. What these sources do not address — biology and paternity tests

The cited materials record births, dates, locations and familial relationships, but they do not include medical records, DNA test results, or detailed statements expressly describing biological parentage beyond the routine “son/daughter of” language used in birth announcements and encyclopedic entries ^{[1] [2]}. Therefore, available sources do not mention DNA testing or any official documentation explicitly framed as “proof” of biological maternity or paternity.

3. How journalists and reference works treat family claims

Reference entries and mainstream profiles treat parentage the way most biographies do: by reporting the couple’s own announcements, hospital and baptismal records, and official royal web pages. For example, the Royal Family website and news outlets recorded Archie’s birth and later Lilibet’s, and profiles summarize those facts without qualification ^{[5] [2]}. This is standard practice: journalists and encyclopedias report the parents named in primary announcements rather than publishing private medical data ^{[3] [4]}.

4. Potential misinformation and what would count as authoritative refutation

Claims that contradict the publicly stated parentage would need primary evidence — such as an official medical statement, legal filing, or verified DNA results — to be authoritative. None of the supplied sources present such evidence disputing Meghan’s maternity or Harry’s paternity; therefore, available sources do not mention any verified refutation of the stated parentage ^{[6] [1]}. If a source among these explicitly refuted a claim, it would be appropriate to cite it; none do.

5. Why some questions circulate and what to watch for

High‑profile families often attract rumors about lineage; those rumors spread faster when private medical details are unavailable. The supplied reporting shows standard practices — birth announced by the parents, entries in reference works, baptism and appearances with grandparents — which is the factual basis for the public understanding that Archie and Lilibet are Harry and Meghan’s children ^{[5] [2]}. Scrutinize any future claims for primary documentation (hospital records, legal filings, or official statements) before accepting them as authoritative, since secondary speculation is common and not present in these sources.

6. Bottom line for readers seeking certainty

Based on the supplied reporting and biographical entries, Archie Harrison Mountbatten‑Windsor and Lilibet Diana Mountbatten‑Windsor are publicly recorded as the children of Prince Harry and Meghan Markle, with births and official acknowledgments documented in mainstream sources ^{[1] [4]}. Available sources do not provide or cite DNA test results or other private medical records; they also do not present any verified evidence that disputes Meghan Markle’s maternity.
