Which Genealogy Website Is Most Accurate? How to Judge It for Scottish Records

There is no single "most accurate" genealogy website, because accuracy is not a property of a brand — it is a property of which layer of record you are looking at on that site. The same platform can show you a flawless scan of an 1861 census page and, two clicks away, a user-submitted family tree that is simply wrong. For Scottish research the official layer is unambiguous: the statutory registers, censuses and church records of National Records of Scotland, published through ScotlandsPeople.

The three layers, ranked

1. Original record images. A photograph or scan of the actual register page, parish book, or passenger manifest. This is the evidence. Everything else is a description of it.

2. Indexes and transcriptions. Someone read the image and typed the names, dates and places into searchable fields. Indexes are how you find records, and they are the layer where most errors live. Treat an index entry as a pointer to an image, never as the fact itself.

3. User-submitted trees and hints. Other people's conclusions. Occasionally excellent and well sourced, frequently copied from other unsourced trees. Useful as a hypothesis generator, worthless as proof.

Ask of any search result: which layer am I looking at? If the site will not show you an image or name the repository and reference, you are on layer two or three.

Why Scottish indexes go wrong in predictable ways

  • Mac and Mc. The same man appears as MacLeod, McLeod and M'Leod across his own lifetime of records. Search all three plus the apostrophe form.
  • Handwriting. In older hands, a long "s" reads as "f," and double-l and double-t ligatures confuse both human transcribers and automated text recognition.
  • Gaelic and anglicized name pairs. A child baptized under a Gaelic form may be indexed under its English equivalent, or vice versa. Scotland's Gaelic-speaking communities are documented in the Scottish Government's Gaelic language policy, and the linguistic overlap matters when you are guessing how a clerk spelled a name.
  • Place names repeat. Dozens of Scottish parishes share name elements. An index that gives you only a county is not enough to identify a family.

What the official platforms do and do not cover

Scotland's statutory civil registration of births, marriages and deaths begins in 1855. Before that you are working from old parish registers and kirk session records, whose survival varies sharply by parish — the point at which many online trees silently invent a generation. Check what actually exists for your parish through National Records of Scotland rather than assuming a gap in a commercial index means a gap in history.

For emigration, the decisive documents are usually on the US side. The National Archives guidance on passenger arrival records explains what ship lists cover for roughly 1820 onward and what they do not — earlier arrivals often have no federal manifest at all, which is the real reason a line goes cold, not a deficiency in any particular website.

For clan and regional background, the Library of Congress Scottish clans resource guide lists vetted databases and printed sources, and the National Library of Scotland holds digitized historic maps that let you place a farm or croft name that no index recognizes.

A five-minute accuracy test for any site

1. Pick an ancestor whose record you already have in hand.

2. Search the site and see whether it finds them with the spelling you know.

3. Open the result and look for the image, repository name, and reference number.

4. Compare three fields — name spelling, exact date, parish — against your known record.

5. Check whether contradicting entries exist and whether the site lets you see them.

A site that passes this on original images is trustworthy for evidence. The same site may still fail badly on trees and hints, and that is normal.

The habit that beats platform choice

Cite every fact to the record that proves it, and record where you looked and found nothing. Doing that makes the platform question mostly moot — and it is the method behind our guides to starting Scottish ancestry research from the United States and to checking whether a tartan is really registered, where the same instinct applies: go to the official register, not the summary.
