Frederick was born in Florence, Italy on 9 February 1840.{{cite web|author1=FamilySearch|title=England and Wales Census, 1881|url=https://familysearch.org/ark:/61903/1:1:QKXQ-THLJ|website=FamilySearch.org|publisher=The Church of Jesus Christ of Latter-day Saints|access-date=27 May 2017|page=RG 11/1887 folio 19 page 1|date=1881}} He was the only son of Frederick Thellusson, 4th Baron Rendlesham, and his wife Elizabeth Charlotte ({{nee}} Prescott) Duff, a daughter of Sir George Prescott, 2nd Baronet, and former wife of General Sir James Duff. His mother died when he was less than one year old.

His great-grandfather, the British merchant and banker Peter Thellusson, was perhaps best known for his "extraordinary will" which "gave rise to an act of Parliament known as the Thellusson act."

Thellusson was educated in England at Eton and Christ Church, Oxford. In 1852, aged twelve, he succeeded in the barony on the death of his father. However, as this was an Irish peerage it did not entitle him to a seat in the House of Lords.{{cite journal|title=Lord Rendlesham: peer, politician and public man|journal=Lambert's Family Almanack for 1912|date=1911|page=49}}

Lord Rendlesham was appointed Sheriff of Suffolk in 1870 and elected to the House of Commons as member of parliament (MP) for Suffolk East at a by-election in March 1874, a seat he held until the constituency was abolished at the 1885 general election.{{cite book |last=Craig |first=F.
