Hi Tim,
This is from memory as I don't have my database on this computer....
Elizabeth Flett married twice.... both husbands were William Qualtroughs...
WilliamQ 1 died in 1701 (not 1801) . He was from Lonan...Eliz Flett and William 1 had the daughter Mary.
Elizabeth Flett widow married again to William Q of Kentraugh, Rushen. in 1704 (I think - check the Qualtrough Genealogies website www.freewebs.com/qualtroughgen and click on Qs of Kentraugh .... They had a son Willliam who married 1 Jane Maddrell in 1730 (Jane died 1736) and 2 Elizabeth Gawn in 1737.....
Elizabeth Flett Qualtrough died in 1742 and is buried in Rushen.
Hope that helps.
Kind regards
Elizabeth.
