Tadlock
A likely English-language surname that probably began as a local or family-name variant of an older place or nickname form.
The #9,237 most common surname in the United States (2010 Census) — about 1 in every 87,637 Americans shares it.
Etymology
Tadlock is a relatively uncommon surname, and its exact origin is not securely documented in standard surname references. It is likely an Anglicized or altered form of an older surname or local name, possibly shaped by dialect spelling and sound changes over time. The first element may reflect a personal name or nickname base, while the second element could be a suffix or reduced place-name ending, but the evidence is too thin for a firm literal meaning.
History
The name is found mainly in English-speaking countries, especially the United States, where it appears to have remained a rare family name. Because it is uncommon and variably spelled, its early history is harder to trace than that of more established surnames. Modern bearers may descend from one or more unrelated lines that adopted the same or similar spelling independently.

Fun fact
Rare surnames like Tadlock are often difficult to pin to a single original place or form because small spelling shifts could create a new recorded surname in parish or census records.
