I see. Thanks, that's very helpful. No, my ancestor was gr-gr-grandfather (John Connor) - and then almost certainly it would seem, his wife my gr-gr-grandmother (Elizabeth (ne Dunn) Connor). Here's why:
1) I have a Maryland land record of Dr. Grafton Bosley leasing a 75'x75' plot of land in Timonium MD on the York Towne Turnpike (now called York Rd.) in 1869 (19 years after they arrived). This plot is definitely where they lived - and two of her sons after her in two side-by-side houses.
2) The reason I think they are friends, or very close business acquaintances is that Dr. Bosley leased that property to Elizabeth for $43 per year. But then, just 2 years later in 1871, he sold her the property for what appears to be an extremely generous price of $250. Both land records are primary records straight out of the MD state archives. So, it appears they had a long and amicable relationship - and it appears that Dr. Bosley was exceedingly kind to them. And so I'm thinking that relationship must have come from a long term working relationship. And if I found his business books - I might gain much data on, for example, what type of farming they did for him, what their roles were, etc. This would really help me put "flesh on the bones" of their lives way back then. Thanks again for your quick reply - J
