Hi again. A lot of what I recall about the Paris family were things I noted many years ago when doing my first Shairp research, but I haven't been that active lately. I think I noted them in old estate censuses and rentals. I just perused about 100 pages of summaries from the Shairp family papers from the The National Archives of Scotland which I found on-line and found the following items about the Paris family which might be helpful. Please note the old spelling of Paris is Pares. I have typed these summaries exactly as in the original. I think missive is letter and tack is a rental agreement.
GD30 item 375: Missive by James Pares to Thomas Shairp of Houstoun to remove from the lands of Nettlehill at Martinmas next. 20/3/1764
GD30 item 669: Tack by Thomas Shairp [Sharp] of Houstoun to John Pares [Paris] tenant at Burslethal [Bracelet Hall] of the lands of Bruslethail in Houstoun in the parish of Uphall and sheriffdom of Linlithgow. 17/10/1750
GD30 item 671:Tack by Thomas Shairp [Sharp]of Houstoun to James Paris, wright in Houstoun, of the lands of White Croft and the lands on the west sdie of Houstoun ground, at present prossessed by the said James Paris and Isobel Hardy [Harie], his mother, for 17 years. 1/3/1753
GD30 item 678: Tack by Thomas Shairp [Sharp] of Houstoun to John Fleming, wright, formerly in Burnhouse, now in Houstoun, of lands and houses in the west end of Houstoun latley possessed by Thomas Craw and lands on the west end of Houstoun lately possessed by James Paris, wright and teinds thereof, for 19 years. 17/11/1761
I'll send you anything else as I come across it, and I'll send you a summary of what was going on in the Shairp's lives too. That time period is when I suspect another Shairp or two may have been illegitimate births as well. I'm just now getting back into my research so I'll keep my eyes open for more Pares/Paris connections.
