Private User suggests a different pedigree for the Edward Scott who married Elizabeth Grome, based on this source:
The Heraldic Journal: Recording the Armorial Bearings and ..., Volumes 1-4. vedited by William Henry Whitmore, William Sumner Appleton. (1865) Page 104-105. < GoogleBooks > "The Scott Family."
I'm snipping so we only focus on the couple of generations and not the entire tree.
THE SCOTT FAMILY.
There are several reasons which lead us to believe that one or more branches of the Scotts of Scott's Hall, co. Kent, settled in New England. There are now extant two ancient manuscript pedigrees of the family, one of which expressly states the fact, and we will consider this first. This roll is now in the possession of Rev. Dr. Jenks, and contains several generations of the ancestors of Sir William1 Scott, who married Anne, daughter of Reginald Pimpe. ....
..... A second manuscript is in the possession of the descendants of Judge James Scott of Newport, R. I. In this the pedigree is continued, in the line of Richard Scott, third son of Sir John Scott and Anne Pimpe.
This Richard Scott married a dau. of George Wettenhall of East Pelham, and had several sons; of whom Edward, third son, married Mary, dau. of John Warren. Their son was Edward Scott of Glemsford, co. Suff., who m. Elizabeth Grome of Suff., and had Edward' and Richard. Edward Scott of Glemsford m. Sarah, sister of Richard Carter of Brookhall, co. Essex, and had Edward, Richard, Frederick, and Matthew. It is thought that Judge Edward Scott was the son of one of these last named four brothers; he came to Newport, about 1710.
It has also been thought that Richard Scott, son of Edward S. of Glemsford, was the person who came to Boston, in 1634, and married Catherine, dau. of Rev. Edward Marbury, sister of the famous Anne Hutchinson. He was a quaker and removed to R. I., where his descendants have been in good standing. However, these affiliations need confirmation by researches in England; as the name is common both in England and this country. ...
This is different from what Geni currently shows as Edward Scott, I, of Glemsford (1546-1627) son of Richard Scott, ll, of Glemsford (1510-1565) & his first wife Joanna Scott
You'll notice that Private User curates the parents of this Edward.
Opinions and more sources more than welcome.
