i know this is some years later, but I am related to the Parkinsons you mention in this thread. Most of my Parkinsons married into the Westmans and Langfords that you name. I think their graves are all over London area! I am from John Parkinson m to Ann Cobb in Co Lois, Ireland, whose parents were Thomas Parkinson married to Elizabeth Mape, born c 1770's in Laois Co, Ireland. Is this the Elizabeth you mention in your message? Most of the Parkinson children emigrated between c 1820 (the eldest daughter Martha was first) and 1847 (my gr-gr-great grandfather above was among this lot), to the London Middlesex Ontario area. Elizabeth, Martha, John and Robert are most of the usual first names in the Langfords, Westmans and Parkinsons, making sorting them out very interesting.
Please let me know if you are still interested in this line. We have a cousin in Ireland (a Langford!) who has been doing research, and there is a book out now on the Langfords and WEstmans, that the Parkinsons are among.
And if you are related to me, even better!
thanks very much
