Lay out the kinds of sources and places in the UK that answer each part (deeds, census-type records, old maps, local archives, newspaper archives), what each one can and cannot tell them, and the sensible order to work in. No URLs — the shape of the search, not links.", "output": "Tracing the history of a 1930s semi-detached house in Leicester is a fascinating project. Because the house was built in the 1930s, you bypass the need for Victorian census records for the house itself, but you hit a \"census gap\" (the 1931 census was destroyed by fire, and the 1941 census was never taken due to WWII). \n\nHere is the sensible order to work in, the sources to use, and what each can and cannot tell you.\n\n### Phase 1: The Starting Point (The House and Its Paper Trail)\nBefore visiting any archives, gather what you already have access to. \n\n**1. Title Deeds and Epitome of Title**\n* **Where to find them:** Check with the solicitor who handled your purchase, your mortgage lender, or your own files. \n* **What they can tell you:** The exact date the land was sold for development, the name of the builder or developer who bought it, the first person to buy the house, and a chronological list of subsequent owners. They often include restrictive covenants (e.g., \"no keeping of pigs,\" \"no building of sheds\") which give a flavour of the developer's intentions.\n* **What they cannot tell you:** Who actually *lived* in the house (people often rented), what the land was used for before the development, or the daily lives of the occupants.\n\n### Phase 2: What Stood on the Land Before (Pre-1930s)\nLeicester expanded rapidly in the 1920s and 1930s, swallowing up former agricultural land and large estates. \n\n**2. Old Ordnance Survey (OS) Maps**\n* **Where to find them:** The Record Office for Leicestershire, Leicester and Rutland (LLRRO), or the National Library of Scotland’s map collection (which covers all of the UK).\n* **What they can tell you:** Look at the 25-inch OS maps from the late 1800s and early 1900s. They will show if your plot was a field, a quarry, part of a large estate, or perhaps an older building that was demolished to make way for the 1930s suburb. \n* **What they cannot tell you:** The names of the people who owned the fields, unless it was a very large, named estate.\n\n**3. Tithe Maps and Apportionments**\n* **Where to find them:** LLRRO.\n* **What they can tell you:** Produced in the 1840s, these map every plot of land in the parish. The accompanying \"apportionment\" document lists the landowner, the tenant, the land use (e.g., arable, pasture), and its acreage. This tells you exactly whose farm or estate your house was built on.\n* **What they cannot tell you:** Anything that happened after the 1840s (unless the maps were later updated, which is rare). \n\n### Phase 3: Who Built It (The 1930s)\nLeicester had many local builders during the interwar housing boom. \n\n**4. Building Control / Local Authority Plans**\n* **Where to find them:** Leicester City Council’s archives, largely held at the LLRRO.\n* **What they can tell you:** Builders had to submit plans to the local authority. If these survive, you will find the exact date the plans were submitted, the name of the builder or architect, the original layout of the house, and the materials used. \n* **What they cannot tell you:** Whether the builder actually finished the job (many went bust), or who bought the house once completed.\n\n**5. Local Newspaper Archives**\n* **Where to find them:** The British Newspaper Archive (accessible via subscription or free at many local libraries), or the local studies section of the LLRRO.\n* **What they can tell you:** Developers often took out large advertisements in the *Leicester Mercury* or *Leicester Chronicle* to sell new estates. Searching for your street name in the early 1930s might yield adverts describing the houses (\"Three bedrooms, modern conveniences, semi-detached...\") and naming the developer.\n* **What they cannot tell you:** Specific house numbers are rarely mentioned in these estate-wide adverts.\n\n### Phase 4: Who Has Lived There (1930s to Present)\nBecause you cannot use the 1931 or 1941 census, you must rely on annual registers and directories to track the occupants.\n\n**6. The 1939 Register**\n* **Where to find it:** The National Archives (usually accessed via major genealogy websites).\n* **What it can tell you:** Taken on the eve of WWII, this is a mini-census. If your house was built by 1939, it will list every resident living there on that specific date, their exact dates of birth, and their occupations. \n* **What it cannot tell you:** Anyone born after 1939, or anyone who moved in during the 1940s or later.\n\n**7. Electoral Registers**\n* **Where to find them:** LLRRO and online genealogy platforms.\n* **What they can tell you:** These are published annually. By looking at the registers for your street from the 1930s to the present day, you can track exactly when families moved in and out, and see the names of the adults living there year by year.\n* **What they cannot tell you:** Children (who cannot vote), transient renters who didn't register, or the relationships between the people listed.\n\n**8. Street and Trade Directories**\n* **Where to find them:** LLRRO and online historical directory projects.\n* **What they can tell you:** Published annually, these list the head of household at each address, and often their occupation (e.g., \"John Smith, Grocer\"). This is excellent for adding colour to the names you find in the electoral registers.\n* **What they cannot tell you:** Other family members, or people who rented rather than owned.\n\n**9. Local Newspapers (Again)**\n* **Where to find them:** British Newspaper Archive, local libraries.\n* **What they can tell you:** Once you have names from the electoral registers or the 1939 Register, search the newspapers for those names alongside \"Leicester\" or your street name. You might find birth, marriage, and death notices, obituaries, court appearances, or even letters to the editor. This is where the house's history comes alive.\n* **What they cannot tell you:** The mundane, everyday lives of the occupants unless they made the news.", "latency_ms": 11745, "cost": 0.0118216, "task_score": 8, "judges": [ { "judge": "anthropic/claude-sonnet-5", "score": 8, "violates": false, "reasoning": "Accurate, well-organized, covers deeds, maps, census/1939 register, directories, newspapers with can/cannot and order.
