McCabe/Donlon/Welch

Looking for information on Lawrence and Bridget McCabe.Their daughter Mary Donlon (why different last name?) married Luke Welch - he was born in Ireland and died 1918 in Clinton, NY.Mary died in 1906 in Clinton,NY.Believe they were from the Sangerfield and/or Brookfield,NY area - verification of this would help.

Luke and Mary's children were Mary(never married), Winafred (b abt 1863), Thomas (b Nov 1864), and Joseph (b Nov 1868)

Any help would be appreciated.
