Looking for Cullen Smale Coffey Maffey Miller Etc of Illinois

I would like to make contact with any descendants of my great granduncle, Patrick Joseph Cullen (1863-1931) who was born in Humewood, Kiltegan, County Wicklow, Ireland. He emigrated to Rockford, Illinois in 1887, where he married Catherine (Katie) Ida Cleary from the west of Ireland in 1890. I believe he was a Weigh master at a stone quarry in the Rockford area. It is said that he survived a hurricane while at work. The following details were freely obtained from various genealogical websites and it is the only information I have of this branch of the family to date.

Patrick & Katie's family:-

1. Loretta Cullen (m. Edmond Smale; family: Donald Smale [m. Louise Stambaugh] & Jean Smale [m. George W. Coffey])

2. Anna Cullen (m. Joseph Maffey; family: Doris Maffey [m. Ralph Miller] & Shirley Maffey [m. Edward C. Dorr & Gunnard E. Sjoblom])

3. Veronica Cullen (died young)

4. William Cullen (m. Anna Peterson; family: Alice [m. Kenneth Lee Darrion] & Loraine Cullen of Seattle. William later m. Ida Westrick)

5. Patrick Cullen (m. Mabel Manning; family: John & Raymond Cullen)

6. Raymond John or John Raymond Cullen (m. Viola Holmquist; family: Thomas Cullen [m. Frances Marshall] & Geraldine Cullen [m. Ralph C. Foster])

7. Lester T. Cullen (family: unknown)

My aim is to make contact with my 3rd cousins, complete the genealogy of this branch of the family, and to share with them the genealogy of our entire Cullen family dating back to 1799 in Ireland. Please submit a comment or contact me through this website if you are related to any of the above. Thank you.
