Documents recorded during his lifetime inconsistently list his name Emanuell Downeing, Emmanuell Downeigne, etc. Insomuch as no known contemporary records exist identifying the exact dates or locations of his birth and death, I've simply denoted 1585 and 1660 based on register entries of his purported baptism and interment (presented below).
A lawyer of the Inner Temple, London, he also resided in Dublin, Ireland; the Massachusetts Bay Colony, America; and Edinburgh, Scotland.
With respect to Mr. Downing's origins, the following was presented in Vol. I, Fifth Series, of the Collections of the Massachusetts Historical Society (1871, p. xxxii)—
"He has sometimes been supposed to have been a son of the Rev. Emanuel Downing, a clergyman of Puritan spirit,… But the Parish Records of St. Lawrence Church in Ipswich, in the County of Suffolk, has the following entry:—
'1585. Emanuell the sonne of George Downing Baptd. the 12 of August.'
Could this have been any other than our Emanuel Downing, and may we not henceforth count him confidently among the natives of that good old County of Suffolk, which supplied so large a quota to our New England emigration, and from which our own Suffolk was named?"
Details of his first marriage may be reviewed by accessing wife Anne's memorial page (linked below).
Regarding his interment, Boyd's London Burials (1538–1853) and the City of Westminster Archives Centre cite the page from St Martin-in-the-Fields' registry entitled "Sepultorum decembris 1660," which documents his burial on the 14th day of that month (December).
Mr. Downing's second wife, the former Lucy Winthrop, survived him.

Following the creation of my original page for Mr. Downing (No. 115517084, added 15 Aug 2013), undocumented and erroneous content from duplicate memorials was merged with my referenced information; out of respect to my ancestor, I removed the compromised page and have recreated the first version here. Requiescat in pace, Grandfather Downing. — A. J. Parker (9 Apr 2020)
