Verlinda and Eleanor: Sisters or Cousins?

Verlinda and Eleanor: Sisters or Cousins?
After a tip-off that John Chappell m Verlinda Harvey (same surname as Thomas Chappell's wife Eleanor Harvey), I've recently tried to find out more about the Harveys of Maryland to confirm that the two Chappell women were related by blood as well as through marriage to these brothers John and Thomas Chappell/Chapple/Chapell.

To refresh your memories, here are the Census entries for Henry Chapple/Chapell/Chappell and his family in 1776 Frederick Co, MD:

From Maryland Records, Volume 1, 1776 Census of Lower Potomack Hundred (Frederick County) page 182, "A List of the Number of Souls Taken & Given in to the Committee of Observation. The Sex & Ages of White and Black, Aug. 22, 1776"

Chapple, Henry 60 Uphane Chapple 55
Thomas 21 Rebecca 19?
George 16

Next door is John Chappell, most likely Henry's son:

John Chapple 30 Verlinda Chapple 20
William Chapple 2 Sarah Chapple 1

I have not found a Maryland Harvey family with an Eleanor and Verlinda Chappell that could be ours yet; however, I have found many Eleanor and Verlinda Harveys whose dates or counties don't match the information that I have for our Eleanor Chappell.

I am sure that I will find their families of origin in time. Verlinda was 15 years Eleanor's senior, according to our census data. If they shared the same surname, it is more likely that they were cousins rather than sisters.

For example: 1776 Prince George's Co, MD Census:

Harvey, Thomas 55
Henry
Elianor
Virlinda

Harvey, James 30
Thomas, Jr. 6
George 3
Mary 30
Elizabeth 2

This is the same year that Virlinda and John Chappell lived next door to Henry, so it can't be the same family; however, in 1776 Eleanor Harvey could have been living in Prince George's County, MD in her father's household with a sister named Virlinda (ages were not recorded in the archive I accessed . . . so I will need to follow up in my research).
