Hi, Great to hear from you but unfortunately it does not look like we are related. I do have considerable info on the Kingscourt area of County Cavan.
I have lots of information on our branch of the Martin family originating from Kingscourt, County Cavan, Ireland. Through the various maternal links we also have information on the families of Patrick Mooney & James Reilly
The earliest record of this branch of the Martin family has been traced back to one James Martin & dates around the mid 17th century. Up to now we have been unable to obtain information regarding James Martin’s forbearers & this is a very high priority as it would take our knowledge to another generation. Our present level of information makes James Martin the Progenitor or Patriarch, in our family line.
I have no information relating to a Daniel Martin, although interestingly enogh several of James Martin's sons settled in the Bronx area which I understand includes Hells Kitchen, in the early 1900's
Sorry that I couldn't respond more positively

Regards
Peter Martin
