Logsdon
A English surname probably from a place-name meaning “Long stone,” with the spelling reduced over time from Longstone to Longsdon and then Logsdon.
The #3,491 most common surname in the United States (2010 Census) — about 1 in every 30,145 Americans shares it.
Etymology
Bardsley treats Logsdon as a reduced form of an older place-based surname, most likely from Longstone. The suggested development is Longstone > Longsdon > Logsdon, with the middle consonants simplified in speech and spelling over time. If this explanation is right, the name ultimately refers to a “long stone” or stone marker near the original settlement.
History
The name is especially associated with Derbyshire in Bardsley’s discussion, and he specifically rejects a derivation from Longden. The surviving spellings show the common surname process of local pronunciation shaping the written form over generations. In later records, Logsdon appears as an established surname in England and, much later, in the United States.

Fun fact
Bardsley explicitly says he first proposed the Longstone explanation and then found Longsdon in Derbyshire records, which he took as supporting evidence.
From the historical record
“don is Longsdon with the n elided. It is equally evident that both Longsdon and Logsdon are not variaota of Longden. which would give a aenaeless signification to the name. We (oay safely presume that Longstone became Longsdon, and then Logsdon. It is pleasant”
