Dear Mary The Kinsella's in my Greene family came from Ballyfad and Knockgreany, Coolgreany (was Co Wicklow, now in Co Wexford).
Patrick greene married Elizabeth Kinsella (born circa 1825)-they were evicted from Ballyfad in the Coolgreany Evictions of 1887.Her father was John Kinsella of Newtown, Coolgreany. Elizabeth had the following brothers and sisters - Mary, Ellen, Pierce, Martin (also evicted from Newtown) and one unknown male who had the following children - Ned, Michael, Mollie and an unnamed female Kinsella.
This may not help you much Mary but it may give you the names of potential places your family may have come from.
I also had a look on my data base and this is what I found Unfortunately, I do not have listed a Laurence or Thomas Kinsella. I have Ellen Devereux married a Bart Browne Ellen Devereux married a Patrick Rossiter
Ellen Kinsella married a James Rossiter in 1819 Ellen Kinsella (b1680) who married a Thomas Harper
Not much help really but they may come in handy sometime Good luck
