The only siblings that I have for Joseph are Mary Jane McCausland, b. 1830 in Donegal Twp., Washington Co, PA, and Maxwell Kirk McCausland, b. 05/17/1844 in VA (part which became WV).Mary Jane was my great grandmother.
I believe their Parents were Maxwell K. McCausland, b 1802 in Berkley Co., VA, and Dorothy Elizabeth (Eliza) Kirk, b. 1808 in PA.
This puts my line in America before the Elizabeth in your line was born (in 1830).Of course there could have been a connection back in Ireland prior to 1802.
