Hi kevi
lovely to hear from you, especially so quickly
We are having the same problem with Hugh, I think a lot of Irish goverment records were burnt at some point, so it's very difficult to trace people.
I think you may be right about the church records being the best option.
Patrick and Jane had a lot of children :
Sarah Hannah Crosby 1865 , who married an Ernest Thacker,
Sidney Crosby 1875-1961
Joseph Crosby 1869
Katherine Crosby 1867-1949, married to WIlliam Burgwin, My great grandfather
Peter Crosby 1859
Hubert Crosby 1862
Elizabeth Crosby 1871 or 1872.
I do know some of who the others married ,but forgot to write it down,sorry.
My nephew as just found, as I am typing this to yourself, a baptism record for John Crosby , father is Hugh, Mother is Catherine Lenahan, parish Creeve,Elphin and Creeve, Diocese Elphin., Carrowngarry Dated 1840 06/12/1840.
Hope this information helps you in your search.
Just wondered if you by chance you had done anchestry DNA. Do you live in the uk , if you don't mind me asking, and my nephew was wondering do you know anyone from the family, especially Ireland.
Hope these questions are not to intrusive.
Hope you are well
