The survey that mapped a nation

The Tithe Commutation Act of 1836 quietly changed the face of rural England and Wales. For centuries, parishioners had paid a tenth of their produce — the original tithe — to support the church and its clergy. Payment in kind was messy, contested and increasingly impractical, so Parliament replaced it with a cash charge: the tithe rentcharge. To calculate what each piece of land should pay, almost every parish was surveyed.

The result was two documents that belong together. First, a map, with every field, meadow, orchard and cottage plot given a number. Second, the tithe apportionment, a written schedule listing who owned what and who farmed it. Most surviving maps date from 1837 to the mid-1840s, although some parishes reused earlier surveys and many were revised well into the twentieth century, right up until the Tithe Act of 1936 finally abolished the charge.

What makes tithe records so valuable is their consistency. Unlike enclosure awards, which cover only part of the country and arrive at wildly different dates, the tithe survey swept across nearly every parish within a single decade. It gives you a snapshot of a community at one moment, drawn to a broadly similar standard, with the same questions asked of every field. Three copies were usually made — one for the parish, one for the diocesan registrar and one for the national collection — which is why so many have survived, scattered between county record offices, cathedral archives and the national archive.

Reading the map and the apportionment together

A tithe map on its own is little more than lines and numbers. The apportionment is what turns it into local history. Each numbered plot on the map corresponds to a row in the schedule, and that row normally gives you:

• Landowner and occupier — frequently different people, which is where patterns of tenancy and estate ownership begin to emerge.
• Name and description of lands — the field name, often the most evocative entry in the whole document.
• State of cultivation — arable, pasture, meadow, orchard, wood, garden, and occasionally "waste".
• Acreage in acres, roods and perches — a full measurement of every parcel.
• Tithe rentcharge — the cash sum apportioned to that plot.

Cross-reference the two and you can reconstruct a farm, a hamlet or an entire estate as it stood in the late 1830s: who held the land, what they grew, how much they paid and how the holdings fitted together.

Field names as local history

The names column is where tithe maps earn their reputation. Entries such as Great Long Meadow, Pigs Croft, Hanging Field, Kiln Field, Coney Grey, Beggars Bush and Chapel Close are not decorative. They hint at former use, lost buildings, soil quality, wildlife, enclosure, ownership and sometimes a long-forgotten dispute.

Many of these names are medieval in origin and appear in documents centuries older than the tithe map; the survey simply fixed them in writing for the first time across a whole parish. Compare them with a modern map and you will often find a survivor — a street name on a housing estate, a farm track, a field still called the same thing by a farmer who has never seen the tithe map.

Buildings, boundaries and lost landmarks

Tithe maps are not only about fields. Farmhouses, cottages, barns, mills, smithies and the occasional ruin are drawn in outline. So are footpaths, lanes, hedgerows, streams, ponds and gates, which means the map can reveal boundaries and routes lost to later road schemes, railway cuttings or development.

Treat the detail with a little care, though. Some maps were surveyed beautifully; others were produced to a minimum standard by local surveyors working to a fixed price, and a number were never formally approved. Where several copies survive, prefer the sealed, approved version. Remember too that buildings are drawn but rarely labelled — you will need the apportionment's description column, or a later Ordnance Survey sheet, to put names to them.

Finding tithe maps for your own patch

• Start with your county record office or local studies library catalogue, where tithe maps are indexed by parish.
• Search the national archive catalogue for "tithe" plus the parish name. Apportionments often survive without their maps, and maps sometimes survive alone.
• Check the diocesan record office as well — the second copy occasionally fills a gap left by a missing parish version.
• Many counties have digitised their tithe maps and published them online, some with a searchable index by field name, landowner or occupier.

Always ask for the apportionment alongside the map. Researchers who request only the map frequently go away disappointed, convinced the record is just a lot of numbered fields.

Getting the most from a tithe map

Tithe records reward company. Enclosure awards and maps often predate them and explain why a landscape looks the way it does. Estate papers, manor court rolls, parish registers, census returns and trade directories let you follow the names you find. Sale particulars from the nineteenth and twentieth centuries will tell you what happened to a farm afterwards, and the tithe files record the negotiation behind the award itself — occasionally revealing argument, compromise and local grievance.

A practical method works well. Pick a property you care about, note its plot number on the map, then trace the owner and occupier names through the census and parish registers. Search the same field name across neighbouring parishes to spot patterns of land use. Ask simple questions as you go: who owned it, who worked it, what grew there, and what has changed since?

The joy of tithe maps is that they capture ordinary places at a turning point, on the eve of railways, agricultural depression and the drift to the towns. A few hours with a map and its apportionment can restore a whole community to view — and often a family story along with it.
