Sir Howland Roberts is well documented & known to have had two daughters; Elizabeth who died an infant and Bridget his eldest child who married Edmund Trench, as well as two sons; Sir Thomas Roberts & Jocelyn Roberts. .
I cannot find any evidence that he had a son named John Spencer Roberts, much less one who married a Dorothy Davye 83 years before he was born...
Erica Howton this profile will be a cuckoo child.
Disconnected Howland Roberts, MP, 3rd Bt. of Glassenbury “cuckoo child.” (What a great phrase.)
Sorry, Diana Raquel Sainz Wilson! Maybe we can find his home elsewhere.
There’s a marriage record:
Dorotheye Davye & John Roberts
Marriage: Mar 5 1588 - Norwich, Norfolk, England
Wife: Dorotheye Davye
Husband: John Roberts
Indexing Project (Batch) Number: I03253-7
System Origin: England-EASy
GS Film number: 1565790
Reference ID: item 12
So the birth date of 1662 is likely a typo.
