Heraldry and the Marsdin Surname
Not every Marsdin is related, but the name itself grew out of Marsden. The name is generally explained as “boundary valley”. Only a small detail separates the spellings: Marsdin has “i” where Marsden has “e”. Before spelling was standardised, one family could appear under several forms. Other spellings include Marsdon.
Heraldry is personal: arms associated with the Marsden surname were borne by specific families, and sharing the name does not mean sharing the blazon. Want more than a summary? See the Marsdin family name pack.
